BetterMac Terms of Use and End User License Agreement

Version: 2026-09-20
Effective date: August 24, 2026
Last updated: September 20, 2026

Important notice: These Terms contain material provisions concerning software-license restrictions, Free limits, product-specific Pro purchase and subscription terms, refunds, suspension and termination, warranties, limitations of liability, and dispute resolution. Please read them in full before accepting, purchasing, or using the product. Where applicable law requires conspicuous notice or separate consent, we will present the relevant term separately at checkout, first launch, or another appropriate point. Silence, a preselected option, or merely browsing the Website will not replace consent required by law.

1. Contracting party, definitions, and scope

1.1 Contracting party. The operator of the BetterMac Website and licensor of each App listed in Annex 2 is Beijing Habitai Technology Co., Ltd, registration or company number 91110108MAKBJBRM9N, with registered address at Room CG05-172, Building 8, Courtyard No.1, Zhongguancun East Road, Haidian District, Beijing, China (referred to as “BetterMac,” “we,” “us,” or the “Company”). Contact details appear in Section 20.

1.2 Product and Services. “App” means each BetterMac-branded macOS application listed in Annex 2, including Better UnArchiver and Better Cleaner, together with the updates we supply for it; where a provision refers to “the App,” it means the application you obtained or used, and the App-specific terms in Annex 2 for that application apply in addition to these Terms. “Website” means bettermac.net and its official language versions. “Services” means the Website, customer support, and—only when expressly made available—the direct checkout, License issuance, activation, device management, License recovery, and other online functions supplied by us. Services supplied by Apple, payment providers, hosting providers, or other third parties are not our “Services.”

1.3 Purchase definitions. An “Offer” is the specific product, license scope, device allowance, term, update entitlement, price, and refund terms displayed before direct checkout. An “Order Confirmation” is the electronic confirmation supplied by the seller or payment provider after a successful purchase. A “Direct License” is a software license issued through the Website and managed through a License key, device pool, or another stated method. A “Pro Entitlement” is the paid feature-unlock entitlement described on the purchase screen.

1.4 Consumers and Business Users. A “Consumer” is an individual acting mainly for personal, household, or other non-business purposes. A “Business User” is a person or organization acting for a trade, profession, institution, or other business purpose.

1.5 Scope. These Terms apply when you access the Website, use the App, contact support, or use an available direct-sales or License Service. Third-party websites, apps, and services are governed by their own terms.

2. Acceptance, eligibility, and electronic records

2.1 Acceptance. After these Terms are presented to you, you accept them by clicking an acceptance control or by downloading, installing, purchasing, activating, or using the relevant App or Service. Merely browsing public pages does not by itself mean that you accept purchase or software-license terms, although the Website-access, security, and intellectual-property rules still apply. If you do not agree, do not download, install, purchase, activate, or use the relevant product or Service.

2.2 Legal capacity. You must have the legal capacity required to enter into this agreement. A person below the age of legal majority where they live should use the product only after a parent or guardian has read and agreed to these Terms. A purchase or personal-information activity that legally requires guardian consent must not be completed independently by a minor. A child under 14 should not independently submit an email address, purchase information, or other personal information to us.

2.3 Acting for an organization. If you accept these Terms for a company, school, institution, or other organization, you represent that you have authority to bind that organization, and “you” includes that organization.

2.4 Accurate information. You must provide accurate purchase, billing, email, and License information that you are authorized to use, and keep information that affects delivery, recovery, or performance reasonably current.

2.5 Electronic form. You agree to contract electronically and to receive Order Confirmations, invoices, service notices, and Terms updates electronically. Where required by law, we will provide a version that can reasonably be retained, downloaded, or printed.

3. Purchase channels, applicable documents, and priority

3.1 Mac App Store. If you obtain the App through the Mac App Store, the applicable Apple Media Services terms also govern purchase, payment, tax, refunds, Family Sharing, download, and restoration. Unless the App Store product page presents a custom end-user license agreement supplied by us, the license to the App is governed by Apple’s standard Licensed Application End User License Agreement (the “Apple Standard EULA”): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

3.2 Relationship with Apple terms. These Terms supplement your relationship with BetterMac concerning App operating rules, support, privacy, the Website, and direct Services. They do not expand Apple’s obligations or conflict with Apple’s Usage Rules. If these Terms conflict with applicable Apple terms concerning an App Store transaction, restoration, Family Sharing, or the scope of the App Store license, the Apple terms control. Non-waivable consumer law always prevails.

3.3 Direct sales. The checkout and Order Confirmation will identify the seller for a direct purchase. The seller may be BetterMac or a third party acting as merchant of record or payment provider. Unless checkout expressly states otherwise, BetterMac remains the software licensor, while the third-party seller’s payment, tax, invoicing, or refund terms may also apply.

3.4 Priority of documents. Subject to mandatory law: (a) the Order Confirmation and Offer control transaction-specific product scope, devices, term, update entitlement, price, and any more favorable refund promise; (b) these Terms provide the general use and licensing rules; and (c) an open-source or third-party license controls only the corresponding component. The Privacy Policy describes personal-information handling and does not replace separate consent where law requires it.

4. Software license

4.1 App Store version. The license for an App obtained through the Mac App Store is granted and limited by the applicable Apple Standard EULA or a valid custom EULA presented in the App Store.

4.2 Direct version. For a Direct License that has been fully paid and has not been refunded, charged back, or revoked, and subject to your continuing compliance with these Terms and the Offer, we grant you a limited, non-exclusive, non-sublicensable license to install and use the applicable App on compatible Macs that you lawfully own or control, up to the quantity allowed by the Offer. Transfer is permitted only if the Offer expressly allows it or applicable law requires it.

4.3 Authorized users. A personal Offer is for the purchaser and any household members expressly permitted by the Offer. A business Offer may be used by authorized people within the purchasing organization and under its control, but the number of devices, users, and deployment method may not exceed the Offer.

4.4 Licensed, not sold. The App and its source code, interface, documentation, trademarks, and other intellectual property are licensed, not sold. We and the relevant rights holders reserve all rights not expressly granted.

4.5 License restrictions. Except to the extent expressly permitted by applicable law, Apple Usage Rules, or an open-source license, you must not: (a) copy, modify, translate, create derivative works from, reverse engineer, decompile, disassemble, or attempt to derive source code; (b) sell, rent, lease, sublicense, publicly distribute, host as a shared service, or permit unauthorized third-party use; (c) remove proprietary notices; (d) bypass payment, Pro, device, activation, security, or access restrictions; or (e) use the App or Services to develop a product that substantially copies them.

4.6 Lawful exceptions. Section 4.5 does not restrict non-excludable rights relating to interoperability, error correction, security research, or other statutory activity, and does not restrict rights expressly granted by an open-source component license. When exercising such rights, you must still comply with law and avoid unnecessary disclosure of our non-public information.

5. Free tier and App Store Pro Entitlements

5.1 Current Free allowance. Unless the released App displays a more favorable allowance before use, the current Free allowance for each App is stated in Annex 2. Successfully completed tasks count against the allowance; failed, cancelled, browse-only, preview, and verification-only actions do not count. If a file or format does not provide enough information for an accurate pre-task estimate, the App may require Pro before or during processing.

5.2 Fair use. The Free allowance may be measured locally by the App. You must not manipulate system time, application data, installations, automation, or another mechanism to reset or bypass the allowance. We may correct an obvious metering error.

5.3 Mac App Store Pro. If offered on the purchase screen, Mac App Store Pro is either a one-time non-consumable purchase or an auto-renewable subscription, as stated in Annex 2 and on the purchase screen. A successful purchase that has not been refunded or revoked, or an active subscription period, unlocks the Pro features identified on the purchase screen in the same App. The purchase screen, StoreKit record, and in-app StoreKit state determine the actual entitlement.

5.4 A purchase model is not a promise of perpetual maintenance. A one-time purchase means that the same Pro Entitlement does not require a recurring fee; an auto-renewable subscription provides the corresponding entitlement only during active paid periods. Neither model promises that the App, App Store distribution, every feature, updates, technical support, third-party components, or compatibility with future macOS versions or hardware will continue forever, and neither automatically includes a separate new product or a future major version expressly excluded at purchase. We will not revoke a valid local paid Pro Entitlement merely because we stop selling or supporting it.

5.5 Restoration and Family Sharing. Restoration of App Store Pro depends on the Apple account, StoreKit, App availability, and Apple rules. Family Sharing is not offered for the Apps currently listed in Annex 2; if we enable it for an App in the future, the purchase screen and Annex 2 will say so. We do not control Apple accounts, storefront regions, purchase restoration, or Apple refund decisions.

5.6 Changes to Free rules. We may reasonably change future Free allowances for capacity, security, abuse prevention, or product-design reasons, with advance conspicuous notice in the App or on the Website. A change applies prospectively and will not reduce a purchased core Pro Entitlement.

5.7 Free trials and introductory offers. Where the purchase screen offers a free trial or another introductory offer, its length, the price that applies after it, the billing period, and how to cancel are as shown on the purchase screen and by the App Store. Eligibility is determined by Apple per subscription group and Apple Account, and is normally available only once per subscription group. Unless you cancel at least 24 hours before the trial ends, the trial converts automatically into a paid subscription charged at the tier you selected; any unused part of a trial is forfeited once you purchase a subscription.

5.8 Auto-renewal, cancellation, and switching tiers within a group. An auto-renewable subscription renews and is charged at the end of each billing period unless you cancel at least 24 hours before the current period ends. Cancellation takes effect at the end of the period already paid for, the Pro Entitlement remains available until then, and paid periods are not refunded pro rata (except as provided by Apple’s refund policies or mandatory law). Switching between tiers of different lengths in the same subscription group is handled under Apple’s rules; a switch between tiers of the same level takes effect on the next renewal date. Payment, charging, renewal, cancellation, restoration, and refunds are handled by Apple under its terms. Restore Purchases in the App does not require an existing Pro Entitlement.

6. Direct Licenses, device pools, and update entitlements

6.1 Conditional application. This Section applies only when the Website purchase page expressly shows that direct sales are available. While direct sales are disabled, no direct purchase contract is formed and no valid Direct License is issued.

6.2 Offer snapshot. Product scope, device limit, authorized users, term, price, update entitlement, and other commercial terms are controlled by the Offer displayed before checkout and retained in the Order Confirmation or at License issuance. Keep your Order Confirmation.

6.3 Perpetual and term Licenses. If an Offer uses “perpetual” or similar language, it means that, absent continuing breach, refund, chargeback, or lawful revocation, you may continue using the versions and entitlements included at purchase without a recurring license fee. It does not promise perpetual updates, support, compatibility with future operating systems, permanent online Services, or automatic rights to a separate new product. A term License is valid only for the period stated in the Offer.

6.4 Bundles and reissues. Bundle products, replacement keys, and reissued keys under one commercial License share the same device pool. Ordinary reissue, recovery, or redelivery does not increase, reset, or duplicate device capacity.

6.5 Key security. A License key may be used only by the lawful purchaser and authorized users. You must not publish, sell, rent, broadly share, post it in a code repository or forum, or deploy beyond the Offer. Contact support promptly if a key is leaked or used without authorization.

6.6 Channels do not interoperate. A Direct License and a Mac App Store entitlement are separate licensing systems. Unless we offer a written migration program, we do not promise cross-channel conversion, merger, exchange, or restoration, and one purchase is not guaranteed to be valid in both channels.

6.7 No automatic renewal by default. A one-time purchase does not renew automatically. A recurring or auto-renewing Offer may be provided only if checkout conspicuously states the period, price, renewal, and cancellation method before purchase and obtains any consent required by law.

6.8 End of activation for a perpetual License. If we permanently discontinue activation Services that are necessary for a valid paid perpetual Direct License, we will take commercially reasonable measures to provide a practical way to continue lawful use or an appropriate remedy, unless prevented by law, a material security risk, a third-party platform restriction, or an insurmountable technical reason. This does not limit non-waivable rights.

7. Orders, price, payment, tax, and refunds

7.1 Formation of a direct contract. A direct purchase contract forms at the time required by applicable law and, in all events, no later than when checkout confirms a successful purchase and makes the Order Confirmation or License available. We will not rely on a standard term stating that no contract exists after payment has been completed. An obvious pricing or configuration error will be handled under applicable law; if a transaction is lawfully cancelled, collected amounts will be refunded promptly to the original method.

7.2 Price and tax. Currency, tax-inclusive or tax-exclusive price, applicable tax, exchange-rate treatment, payment method, seller, and invoicing arrangements are shown at checkout and in the Order Confirmation. You authorize the seller and its payment providers to process the displayed amount and represent that you are authorized to use the payment method.

7.3 App Store transactions. Apple handles payment, tax, receipts, refunds, and purchase restoration for App Store transactions under Apple’s terms. Refund requests generally should be submitted through Apple, but this does not prevent you from asserting against us any legal right relating to product defects, misdescription, or another matter for which BetterMac is responsible.

7.4 Direct refunds. Direct refunds are administered by the seller identified at checkout and in the Order Confirmation. Any more favorable refund promise in the Offer controls. These Terms do not exclude remedies for non-conformity, incorrect delivery, duplicate charges, fraudulent transactions, or another situation in which law requires a refund, repair, repeat performance, price reduction, or termination.

7.5 Immediate supply of digital content. If applicable law gives a withdrawal or cooling-off right for remotely purchased digital content, we will obtain any required express request to begin supply immediately, acknowledgment of the legal consequence, and confirmation in the Order Confirmation. Downloading, activation, or use alone will not be treated as a waiver where law requires an express acknowledgment. See Annex 1 for regional notices.

7.6 Refunds, reversals, and chargebacks. A confirmed refund, payment reversal, or chargeback may cause the corresponding Pro Entitlement, Direct License, or device activation to be revoked. If you believe a charge is incorrect, contact the seller or support@bettermac.net first. We will not treat a good-faith payment dispute that is still under reasonable review as fraud merely because it was raised.

7.7 Payment security. Do not send a full card number, security code, online-banking credential, Apple account password, or other payment-authentication information to support. We will not request that information through ordinary support email.

8. License recovery and device management

8.1 Recovery. When direct recovery is available, we may use a verified email, one-time link, or another reasonable identity check to provide masked License and device information. Recovery links, sessions, and verification codes are sensitive credentials and must not be forwarded, publicly screenshotted, or sent to support staff.

8.2 Device deactivation. The current self-service rule permits no more than three successful device deactivations for each Direct License in a rolling 30-day period. Reactivating a device does not restore a deactivation already used in that period. We may adjust self-service limits for security, abuse prevention, or operational reasons, but will not unreasonably prevent a lawful purchaser from replacing, repairing, or disposing of a device, and will give reasonable advance notice of a material tightening.

8.3 Support handling. Reset-all, revocation, key reissue, exceptional recovery, or high-risk actions may require a support case, proof of the order or email relationship, additional identity checks, and manual review. We may reject a request that cannot reasonably be verified, appears fraudulent, or would harm another rights holder, and will provide a reasonable explanation and appeal channel unless the matter is urgent.

8.4 Device transfer. Before selling, transferring, repairing, disposing of, or otherwise losing control of a Mac, deactivate the old device in a trusted environment and remove any App copy, key, or local credential you are no longer entitled to use.

9. Files, passwords, output, and backups

9.1 Local processing. The App’s core processing functions, as described for that App in Annex 2, run locally on your Mac. The App does not automatically upload the files or content you process to us. Support attachments are transmitted only when you expressly select and separately submit them, as described in the Privacy Policy.

9.2 Authorized content. You must have the right to access, decrypt, copy, modify, compress, extract, retain, and share the files you process. We do not obtain ownership of your files.

9.3 Independent backup. Before processing an important file, the only copy, or high-value data, keep a verifiable independent backup and confirm destination space, permissions, and path. The App is not a backup system and should not be the workflow used to preserve the only copy.

9.4 Technical limits. A task may fail because of corruption, a missing volume, a wrong password, inadequate storage, permissions, paths, symbolic links, the file system, third-party format differences, system failure, or power loss. You are responsible for the selected source, password, destination, overwrite setting, output, and subsequent sharing.

9.5 Recovery and integrity features. Where an App provides a salvage, repair, recovery, or integrity-check feature, its scope and limits are stated in Annex 2. Such a feature does not guarantee recovery of lost or damaged data, and integrity checks, safety warnings, and path protections do not replace professional malware scanning, forensics, or data-recovery services.

9.6 Passwords. A content password, such as an archive password, is used locally for the current action by default and enters macOS Keychain only if you expressly choose to save it. You are responsible for keeping passwords. We generally cannot recover a lost encryption password.

10. Permitted and prohibited use

You may use the App, Website, and Services only for lawful and authorized purposes. Except where applicable law expressly permits, you must not:

• process content you are not authorized to access, decrypt, copy, or share, or infringe intellectual property, privacy, trade-secret, personality, or other rights;
• create, distribute, or facilitate malware, ransomware, phishing material, unlawful content, or files used for attacks, fraud, harassment, or stalking;
• bypass passwords, digital-rights management, access controls, safety warnings, sandbox permissions, payment, device, or rate limits;
• interfere with a Service, conduct denial-of-service or automated abuse, scrape non-public data, or probe, scan, or test an interface or system not made public;
• forge, leak, sell, rent, or broadly share a License key, order credential, recovery link, or administrator credential;
• manipulate system time, files, receipts, device identifiers, App data, or communications to bypass a Free allowance, purchase verification, refund revocation, or device restriction;
• operate the App as an unauthorized hosted, shared, resale, or third-party bulk-processing service;
• violate applicable export-control, sanctions, import, or encryption laws, or supply the product to a prohibited person or territory; or
• use UnRAR source code to develop a RAR-compatible compressor or recreate the proprietary RAR compression algorithm, or otherwise violate a third-party component license.

11. Features, compatibility, updates, and discontinuation

11.1 Actual functionality. Actual App capabilities are defined by the released version, in-app interface, purchase screen, and then-current format matrix. A Website preview, roadmap, or “planned” feature is not a delivered commitment unless expressly included in the Offer at purchase.

11.2 Current format and capability boundaries. Unless the released version expressly states otherwise, the supported formats, read-only limitations, and other capability boundaries of each App are stated in Annex 2. Third-party formats, encryption methods, and file variants may differ in compatibility.

11.3 System requirements. Before purchase or use, confirm the required macOS version, Mac architecture, storage, file system, formats, and other technical requirements. Changes to the operating system, hardware, Apple rules, or third-party components may affect functionality or compatibility.

11.4 Updates. We may provide updates for security, compliance, error correction, compatibility, performance, platform rules, or third-party licensing. Unless an Offer or applicable law requires otherwise, we do not promise a particular update frequency, support period, or future feature. Refusing a necessary update may cause a function to become unavailable or increase security risk.

11.5 Purchased core entitlement. If we make a material adverse change to a purchased core Pro Entitlement or paid Direct License, we will provide reasonable advance notice and, to the extent required by law, an appropriate remedy such as correction, replacement, continued use, price adjustment, refund, or termination. New, experimental, Free, and non-core online functions may be adjusted separately.

11.6 Ending sales or support. We may discontinue sales, download, updates, support, or an online function, with advance notice where reasonably practicable. Discontinuing sale or support does not automatically revoke a valid purchased local license, although continued use may still depend on the operating system, App Store availability, activation Services, security, and third-party dependencies.

11.7 Beta features. A beta, preview, or prerelease feature may be unstable, changed, or discontinued and must not be used for the only copy, production-critical data, or high-risk data. Additional beta terms may apply.

12. Intellectual property, third-party components, and feedback

12.1 BetterMac rights. BetterMac, the names of the Apps listed in Annex 2, the interface, documentation, Website content, graphics, logos, and related materials are protected by applicable intellectual-property laws. Without written permission, you must not use our marks, trade dress, or marketing material to imply endorsement, partnership, or affiliation.

12.2 Your files. You retain rights in your lawful files and content. You grant only the limited permission necessary to carry out a local action or support request that you expressly initiate.

12.3 Third-party software. An App may include third-party components supplied under their own licenses; the components included in each App are listed in Annex 2. If a third-party license conflicts with these Terms, it controls for that component. The per-App component inventory and the full license texts appear on the Website’s Open-source Notices page at https://bettermac.net/licenses/ (English: https://bettermac.net/en/licenses/).

12.4 Feedback. If you voluntarily submit a suggestion, idea, or product feedback that does not contain confidential information, you grant us a worldwide, non-exclusive, perpetual, irrevocable, royalty-free right to evaluate, improve, and develop products using that feedback. This grant does not cover your file contents, personal information, or material that you clearly identify as confidential and that we agree in writing to receive in confidence.

13. Privacy and customer support

13.1 Privacy Policy. The categories, purposes, legal bases, recipients, cross-border arrangements, retention, security measures, and rights channels for personal information are described in the then-current BetterMac Privacy Policy and any legally required supplemental notice. Accepting these Terms is not blanket consent to non-essential personal-information processing.

13.2 Support materials. The website “Contact us” form and in-app feedback are available only when the relevant released product version and production support service display them as available; the relevant product page and App state the categories and entitlement scope currently accepted. Text feedback can be submitted without attachments. Website PNG/JPEG images, App-window screenshots, and redacted diagnostics packages are entirely optional, and you must preview and separately consent to each attachment. A website submission can leave a recoverable unverified draft if an upload or response fails; retrying does not itself verify the email or confirm successful submission. Draft retention and fresh attachment-consent requirements are described in Section 4.4 of the Privacy Policy. If the device is offline or the support service is unavailable, email support@bettermac.net. Before submission, remove unrelated personal information, filenames, paths, License keys, passwords, and trade secrets.

13.3 Support scope. Unless an Offer or mandatory law requires otherwise, support is provided according to available resources and does not promise a fixed response time, resolution time, duration, or support for every old version.

13.4 Apple’s role. BetterMac, not Apple, is responsible for App maintenance and support, product claims, and matters that law assigns to the developer. Apple has no obligation to provide BetterMac customer support except as expressly stated in Apple’s terms.

14. Suspension, restriction, and termination

14.1 Online functions. We may temporarily suspend or restrict the Website, recovery, activation, device management, or another online function for maintenance, a security incident, fraud prevention, a legal requirement, a third-party outage, or a serious breach. Where reasonably practicable, we will limit the impact and restore the Service.

14.2 License action. For material breach, fraud, payment theft, a confirmed chargeback, key leakage, deployment beyond the licensed scope, circumvention, or unlawful use, we may request evidence, restrict activation, suspend, or terminate a Direct License. A curable, non-urgent breach will ordinarily receive a reasonable explanation and opportunity to cure.

14.3 Urgent cases. We may act immediately in response to an active security risk, evident fraud, a legal order, an urgent third-party rights claim, or conduct likely to cause material harm, and will give notice afterward where lawful and reasonably practicable.

14.4 App Store entitlement. An App Store refund, transaction reversal, or change in Apple-account or StoreKit status may cause Pro to end under Apple rules. Termination of the App Store license is also governed by the applicable Apple EULA.

14.5 Termination by you. You may stop using and delete the App at any time and may request an available refund or exercise statutory rights through the applicable purchase channel. Merely stopping use does not create a refund right beyond the purchase rules or law.

14.6 Effect of termination. When a license ends, you must stop using the terminated portion and delete copies and credentials you are no longer entitled to retain. Termination does not affect accrued payment, refund, damages, intellectual-property, confidentiality, liability, dispute, or other provisions that by nature or law continue.

14.7 Appeal. Except in an urgent security or legal case, we will provide a reasonable explanation and contact channel. You may send the order, License information, and relevant facts to support@bettermac.net for review.

15. Warranties, disclaimers, and statutory rights

15.1 Non-waivable rights. These Terms do not exclude, limit, or replace a consumer guarantee, quality standard, update duty, repair, repeat performance, price reduction, refund, termination, or damages right that cannot lawfully be waived. Rights vary by location.

15.2 As available. To the maximum extent permitted by law, except for an Offer, release note, or other express written promise made by us, the App, Website, and Services are supplied in their then-available condition. We do not warrant uninterrupted, error-free, completely secure operation, fitness for every purpose, or compatibility with every file, archive variant, password, operating system, hardware platform, or third-party system.

15.3 Data and security limits. We do not warrant that salvage will recover data, that an integrity check will identify every issue, or that a safety warning will detect all malicious content. An independent backup before processing important files is a necessary risk-control measure.

15.4 App Store warranty. The warranty and refund arrangements in the applicable Apple EULA apply to the App Store version. Apple may refund the purchase price under its rules if the App fails to conform to an applicable warranty, but Apple has no other warranty obligation except as stated in Apple’s terms. BetterMac remains responsible for product matters assigned to us by law.

15.5 No expanded warranty. Support staff, Website articles, and informal communications do not create a warranty beyond the written Offer and applicable law unless expressly confirmed in writing by our authorized representative.

16. Limitation of liability

16.1 Liability not limited. These Terms do not exclude or limit liability for fraud, wilful misconduct, gross negligence, death or personal injury caused by negligence, or any consumer, data-protection, intellectual-property, or other liability that cannot lawfully be excluded or limited.

16.2 Consumers. If you are a Consumer, we are responsible for loss caused by our breach of these Terms or failure to use reasonable care that was reasonably foreseeable when the contract was made. We are not responsible for profit, revenue, business opportunity, goodwill, or business-interruption loss arising solely because you used a consumer product for business. Responsibility for loss caused by unauthorized files, a wrong password, failure to back up, disregarding a clear warning, an unsupported environment, or an inherent third-party-file defect is determined under applicable law and each party’s fault.

16.3 Indirect loss for Business Users. If you are a Business User, to the maximum extent permitted by law, neither party is liable for indirect, incidental, special, punitive, or consequential loss, or for loss of profit, revenue, goodwill, business opportunity, anticipated savings, data, or business interruption, even if advised that such loss was possible.

16.4 Business User cap. For a Business User, to the maximum extent permitted by law, our aggregate liability arising from the same product, Offer, or event will not exceed the greater of: (a) the amount actually paid for the App, Direct License, or Service giving rise to the claim; or (b) US$100 or the local-currency equivalent. For a completely free Service, the aggregate cap is US$50 or the local-currency equivalent. This cap does not apply to liability listed in Section 16.1.

16.5 Mitigation and aggregation. Each party must take reasonable steps to reduce avoidable loss. Related events are treated as one event. These limitations apply to contract, tort, statutory duty, misrepresentation, and other causes of action, but do not duplicate or reduce a minimum remedy required by law.

17. Changes to these Terms and Services

17.1 Versioning. We will publish a version number, effective date, and last-updated date and retain or make historical versions reasonably available.

17.2 Material changes. We will give advance conspicuous notice through the Website, App, email, or another appropriate channel of a material adverse change to your rights or obligations and obtain renewed consent where law requires it. Silence, continued browsing, or a preselected option does not replace express consent required by law.

17.3 No retroactive reduction. New Terms generally apply only to use, online Services, and transactions after their effective date and do not automatically reduce the core license, term, device allowance, or refund promise for a completed purchase. If a change is required by law, security, or third-party platform rules, we will provide notice and an appropriate remedy where reasonably possible.

17.4 Rejecting a change. If you do not accept a material change that requires consent, you may stop using the affected future online Service. A purchased local license and accrued statutory rights will be handled under the purchase-time terms and applicable law.

18. Governing law, disputes, and consumer channels

18.1 Informal resolution. We encourage you to contact support@bettermac.net first and provide the order number, License information, issue, and requested resolution. The parties should attempt good-faith resolution within a reasonable period. This step does not prevent emergency relief, a filing before a limitation period expires, or use of a statutory complaint channel.

18.2 Governing law. These Terms and your relationship with BetterMac are governed by the laws of the People’s Republic of China, without depriving a Consumer of mandatory protection under the law of their habitual residence or place of transaction.

18.3 Forum and arbitration. If you are a Business User, then except where mandatory law provides otherwise, any dispute arising out of or relating to these Terms shall be submitted to the Beijing Arbitration Commission/Beijing International Arbitration Court (BAC/BIAC) for arbitration under its arbitration rules in force at the time of filing; the seat of arbitration is Beijing, China, the language of the arbitration is Chinese, and the award is final and binding on both parties. If you are a Consumer, that arbitration agreement does not apply to you. A Consumer’s dispute may be brought before the competent courts of the People’s Republic of China, and a Consumer may in any event bring or defend a claim in the courts of their residence or another court available under applicable law.

18.4 Other remedies. You may use a consumer organization, market regulator, data-protection authority, mediation body, or another legally available channel. Apple is not a contracting party to a dispute between you and BetterMac except where Apple’s terms or law states otherwise.

19. General

19.1 Entire agreement. These Terms, the Offer, Order Confirmation, applicable regional supplement, and any policy expressly incorporated form the entire agreement on the relevant subject. The Privacy Policy and open-source licenses apply according to their own nature.

19.2 Assignment. You may not assign these Terms or a Direct License without our written consent, except as allowed by the Offer or applicable law. We may assign rights and obligations in a merger, reorganization, asset transfer, or business succession if this does not materially reduce Consumer or purchased-license rights and we provide notice as required by law.

19.3 Severability. If a provision is invalid, unlawful, or unenforceable, it will be adjusted or severed only to the minimum extent necessary, and the remaining provisions will continue. Severability must not be used to expand an invalid exclusion or limitation.

19.4 No waiver. A delay in exercising a right is not a waiver. A waiver applies only to the specific circumstance expressly identified in writing.

19.5 Events beyond control. To the extent permitted by law, a party is not in breach for delay or interruption caused by an event beyond its reasonable control, provided that it takes reasonable steps to reduce the effect. This does not excuse an accrued refund, data-protection duty, security notice, or another obligation that cannot lawfully be excluded.

19.6 Notices. We may give notice through the App, a conspicuous Website notice, the order email, or another contact you provide. You must keep contact information current. A legally required form or delivery method controls.

19.7 Third-party beneficiaries. Except for rights granted to Apple and its subsidiaries under the applicable Apple EULA, these Terms create no directly enforceable contractual right for a third party.

19.8 Language. The Chinese and English versions are intended to have the same meaning. If a conflict cannot be resolved by consistent interpretation, the Chinese version controls, except where that would reduce mandatory Consumer rights or local law requires the local-language version to control.

19.9 Headings and relationship. Headings are for convenience only. The parties are independent contracting parties, and these Terms do not create a partnership, agency, employment, franchise, or trust relationship.

Annex 1: Regional consumer notices

A. Consumers in mainland China

1. For software or other digital goods supplied by online download, activation, or immediate delivery, the seven-day no-reason return right may not apply after supply begins where law permits and conspicuous pre-purchase notice has been provided. This does not affect rights arising from non-conformity, false or incorrect description, duplicate charging, non-delivery, or another statutory ground, including repair, repeat performance, refund, termination, or damages.
2. Standard terms concerning price, features, devices, term, refunds, risk, suspension, liability, and disputes should be presented conspicuously, and you may ask us to explain them. A term that unfairly excludes Consumer rights, relieves us of legal responsibility, or unreasonably increases Consumer responsibility is ineffective.
3. When direct sales open, the business identity, registration or other legally required disclosure, contract steps, order-correction method, transaction record, invoice, and complaint channel should be displayed through the Website or checkout as required by law.

B. Consumers in the European Economic Area and the United Kingdom

1. You may ordinarily have a statutory withdrawal period for remotely purchased digital content. If you expressly request supply to begin during that period, acknowledge that the corresponding withdrawal right will be lost when supply begins, and the seller provides the required confirmation, the right may end under local law. If the required request, acknowledgment, or contract confirmation is not completed, downloading or using the content alone does not necessarily end the right.
2. Digital content must still conform to description, meet applicable quality and fitness requirements, and receive legally required updates. A lack of conformity may give rights to bring the content into conformity, a price reduction, termination, and a refund.
3. Governing-law and forum provisions do not restrict mandatory Consumer rights under the law of your habitual residence or your ability to use a locally available court.

C. Other locations

If the law where you live provides a warranty, refund, cancellation, quality, update, privacy, or dispute right that cannot be waived by contract, that right continues and prevails over a conflicting provision of these Terms.

Annex 2: Covered applications and App-specific terms

These Terms apply to each BetterMac-branded macOS application listed in this Annex. Sections 1 to 20 apply to every App; the entry for an App adds or specifies terms that apply only to that App. Adding a new App to this Annex does not change the terms that apply to an App you already obtained.

A. Better UnArchiver

• Application: Better UnArchiver for macOS, bundle identifier net.better.mac.unarchiver.
• Distribution: Mac App Store. Website direct sales are not open for this App. Section 6, Sections 7.1, 7.2, 7.4 and 7.5, and Section 8 apply only if and when the Website purchase page expressly shows that direct sales are available.
• Core local processing (Section 9.1): compression, extraction, listing, preview, integrity checking, and salvage run locally on your Mac.
• Free allowance (Section 5.1): 20 successfully completed tasks in each local calendar month. For each task, both the selected input total and the App’s pre-task estimate of expanded or output size must not exceed 100,000,000 bytes. Successfully completed compression, extraction, and salvage tasks count. Failed, cancelled, browse-only, Quick Look, and integrity-test actions do not count.
• Pro Entitlement (Section 5.3): a one-time, non-consumable Mac App Store in-app purchase. It is not a subscription and does not renew.
• Family Sharing (Section 5.5): not offered for this App.
• Archive creation (Section 11.2): ZIP, 7z, TAR, TAR.GZ, TAR.BZ2, and TAR.XZ; archive encryption is available only for ZIP and 7z.
• Read-only formats (Section 11.2): RAR and RAR5 are extraction-only. The App does not create RAR archives, does not recreate the proprietary RAR compression algorithm, and does not repair RAR recovery records. ARJ is read-only. DMG support is limited and read-only and does not replace macOS Disk Utility.
• Salvage (Section 9.5): salvage only attempts to rebuild readable content into a new ZIP or 7z archive. It does not modify the source archive, does not guarantee recovery of lost or damaged data, and does not repair a RAR recovery record.
• Passwords (Section 9.6): an archive password is used locally for the current action and is written to the macOS Keychain only if you expressly choose to save it. A saved password is stored on the current device only and is not synchronized to iCloud.
• Third-party components (Section 12.3): libarchive, liblzma, 7-Zip, and UnRAR.

B. BetterMac bmtop

• Application: BetterMac bmtop for macOS, command name bmtop.
• Distribution and license: distributed free through GitHub Releases, Homebrew, and source code under the MIT License. This App is not distributed through the Mac App Store or direct website sales and has no Pro, subscription, License activation, or refund flow.
• Core local processing (Section 9.1): reading, displaying, and exporting process and system metrics occur locally on your Mac. The App has no telemetry or runtime network client.
• Hardware capability: Apple Silicon can expose native SoC power, frequency, temperature, and fan metrics. On Intel or where a system capability is unavailable, the corresponding metric is omitted; equal data is not guaranteed on every Mac.
• Process control (Section 9.5): terminating or force-killing a process must be explicitly initiated and confirmed by you. The PID and process start time are revalidated before a signal is sent. You remain responsible for judging the risk of unsaved work, service interruption, or system impact.
• Permission boundary: normal monitoring needs no administrator access. Enhanced sampling and operations on another user’s process may invoke a constrained sudo path at your express request. The TUI does not run as root or store passwords.
• Energy notice: estimated per-process watts are an attribution model derived from measured package power and process resource share, not a direct per-process power measurement.

C. Better Monitor

• Application: Better Monitor for macOS, bundle identifier net.better.mac.monitor.
• Distribution: distributed free through Homebrew Cask and signed direct releases. It has no subscription, paid entitlement, License activation, or refund flow.
• Core local processing: process and system monitoring, local history, network and port inspection, and startup-item inspection run on your Mac. The app does not automatically upload monitoring data.
• Connected features: public-IP lookup is user initiated; optional AI summaries send the selected process snapshot to the AI provider you configure. The provider’s terms apply to that request. Support is available through the support URL shown by the app.
• Operation boundary: process termination and startup-item changes require your explicit action and may be refused by macOS permissions or system protections. The app does not guarantee that every process, port, connection, or sensor is visible.

D. Better Cleaner

• Application: Better Cleaner for macOS, bundle identifier net.better.mac.cleaner.
• Support materials and connectivity (Section 13.2): opening the in-app Support Center reads a support configuration (available categories, size limits, service availability) from our support service once; nothing you have typed is sent unless you submit a case. Text feedback can be submitted independently. App-window screenshots and redacted diagnostics packages are entirely optional, must be separately previewed and consented to, and are subject to the individual and combined limits shown in the App and support service. Available categories and entitlement requirements are shown by the released App and production support service.
• Distribution: Mac App Store. Website direct sales are not open for this App. Section 6, Sections 7.1, 7.2, 7.4 and 7.5, and Section 8 apply only if and when the Website purchase page expressly shows that direct sales are available.
• Core local processing (Section 9.1): scanning for large files, exact duplicate files (SHA-256 plus byte-by-byte verification) and similar images, storage-usage analysis, identifying development build artifacts and tool caches, browsing installed applications and their associated files, and the clean-up and uninstall actions you confirm all run locally on your Mac, within folders you have expressly authorized through the system folder picker.
• Authorization scope (Section 9.1): the App accesses only folders you expressly authorize (persisted as macOS security-scoped bookmarks, removable at any time in Settings) and the list of installed applications that macOS lets an App enumerate. The App Store build does not clean system caches, system logs, or other unauthorized locations.
• Development build artifacts (“Developer Storage”, Section 11.2): within the folders you authorized, the App can identify build directories, dependency caches, and tool caches, and grades them by safety: rebuildable items can be cleaned, review-required items are left to your judgement, and items marked report-only show their size and are not offered for removal. The App does not install, maintain, repair, or configure any system-level developer tool or runtime.
• Deletion behavior (Section 11.2): clean-up and app uninstall move items to the Trash and record a deletion receipt; they do not erase files directly, and you can restore items from the Trash. Duplicate clean-up always keeps at least one copy in each duplicate group, and similar-image clean-up requires you to designate the image to keep.
• Free allowance (Section 5.1): scanning, viewing results, Storage Analysis, and reviewing applications and leftover files are free and unlimited. Up to 1,000,000,000 bytes in total can be cleaned (moved to the Trash) free of charge in each local calendar month; that allowance is shared by every clean-up feature of this App, and app uninstall and Developer Storage clean-up also count against it. Once the allowance is reached, remaining items are not cleaned and further cleanup requires the Pro Entitlement. The allowance resets with each local calendar month.
• Pro Entitlement (Section 5.3): the only Pro entitlement is removal of the monthly clean-up byte cap (unlimited cleanup). No clean-up feature of this App is Pro-only: app uninstall, leftover-file clean-up, similar-image clean-up, and Developer Storage clean-up can all be performed within the free allowance. Pro is an auto-renewable Mac App Store subscription offered in one subscription group with two tiers, monthly and yearly; price, billing period, and trial terms are displayed by the App Store on the in-app purchase screen, and these Terms do not set the price.
• Free trial and renewal (Sections 5.7 and 5.8): both the monthly and the yearly tier offer a one-week free trial to eligible accounts; eligibility is counted per subscription group and is normally available only once. Trial conversion, auto-renewal, cancellation, pro-rata refunds, and switching tiers within the group are governed by Sections 5.7 and 5.8.
• Family Sharing (Section 5.5): not offered for this App.
• Third-party components (Section 12.3): this App currently contains no third-party components.

E. Better Share

• Application: Better Share for macOS, bundle identifier net.better.mac.share.
• Distribution: Mac App Store, free of charge. This App has no Pro, subscription, License activation, or refund flow. Website direct sales are not open for this App, and Section 6, Sections 7.1, 7.2, 7.4 and 7.5, and Section 8 do not apply to it.
• Core local processing (Section 9.1): device discovery, device binding, sending and receiving files and folders, and the browser share page are all provided locally by your Mac within your LAN. The App does not relay data through a BetterMac server and has no telemetry or runtime internet client.
• Device binding and access control: native direct transfer requires binding through a QR scan and a 6-digit verification code, after which transfers are TLS-PSK encrypted. The browser channel controls access with one-time link tokens, expiry, an optional guest PIN, and a guest upload policy (require confirmation / accept automatically / refuse); its page is served over HTTP within the LAN. You remain responsible for judging how trustworthy your network is and for safeguarding share links and PINs.
• Responsibility for shared content (Sections 9.2 and 10): you are responsible for the content you send, receive, or share with visitors holding a link, and for its lawfulness. The risk column in the receive review is a heuristic based only on the file extension and is not a malware scan or a security guarantee (Section 9.5).
• Third-party components (Section 12.3): FlyingFox (MIT License).

F. Better Calc Pro

• Application: Better Calc Pro for macOS, bundle identifier net.better.mac.calc.
• Distribution: Mac App Store. This App has no Pro Entitlement, subscription, License activation, or in-app purchase; any transaction through which you obtain the App from the Mac App Store is handled by Apple as the seller. Website direct sales are not open for this App, and Section 6, Sections 7.1, 7.2, 7.4 and 7.5, and Section 8 do not apply to it.
• Core local processing (Section 9.1): expression evaluation, the worksheet, variables, history, unit conversion, the formula library, and the command palette all run locally on your Mac. The App has no telemetry component; its only network request fetches European Central Bank reference rates through the independent third-party service api.frankfurter.dev.
• Exchange rates and conversion results (Section 9.5): rates are European Central Bank reference rates provided through the third-party service api.frankfurter.dev, cached with a timestamp. They may lag live market prices, are for reference only, and are not financial, tax, or investment advice. Fetching rates for the first time needs a connection; offline, the last successful rates are reused. You remain responsible for verifying any figure used in an actual transaction, tax filing, or contract.
• Clipboard and permissions: the clipboard is read only while you have pinned the window on top, and only its arithmetic part is used; the App requests no system permissions.
• Third-party components (Section 12.3): this App currently contains no third-party components.
