Welcome to AudioCutPro (the "App"). These Terms of Service (the "Terms") form a legal agreement between you and Hangzhou Huanyin Technology Co., Ltd. (the "Company," "we," "us," or "our"), the developer and operator of AudioCutPro, governing your download, installation, registration, and use of the App and the related services. Please read these Terms carefully before using the App, particularly the clauses in bold, and make sure you understand and accept them. By tapping accept or by starting to use the App, you agree to be bound by these Terms in full.

If you do not agree with any part of these Terms, please stop downloading or installing the App and uninstall it immediately.

1. Acceptance and Amendments

1.1 You must have the legal capacity required by applicable law in order to use the App. Minors should only use the App with the consent of, and under the supervision of, a parent or legal guardian; see Section 11.

1.2 We may revise these Terms from time to time to reflect legal, regulatory, or product changes. The revised version will be communicated through in-app notice, website announcement, or banner. Continued use after the effective date constitutes acceptance of the revised Terms. If you do not accept the changes, you must stop using the App.

2. Description of the Service

2.1 AudioCutPro is a local-first audio and video editing toolkit for iPhone and iPad. Core features include but are not limited to:

• Waveform trimming, speed and pitch shifting, volume and fade controls, denoise, mixing, equalizer, compression, reverse, and merge;
• Multi-track timeline editing with real-time effects preview;
• AI vocal / instrumental / drums / bass separation powered by the Demucs model;
• Video ↔ audio conversion, audio track replacement, and split/combine;
• Format conversion (MP3 / M4A / WAV / AAC / FLAC / AIFF), iPhone ringtone maker;
• Real-time recording and Wi-Fi LAN file import.

2.2 The overwhelming majority of these features run entirely on your device. Only AI Vocal Separation transmits the audio segment you select to our server for AI inference. See the Privacy Policy for details.

3. License Grant

3.1 Subject to your compliance with these Terms, we grant you a revocable, non-exclusive, non-transferable, non-sublicensable, limited, non-commercial license to download, install, and use the App on Apple devices that you own or lawfully control.

3.2 You shall not:

• Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the App;
• Modify, adapt, translate, or create derivative works of the App;
• Remove, obscure, or alter any copyright notices, trademarks, or other proprietary marks;
• Rent, lease, sell, resell, sublicense, distribute, or otherwise transfer the App or any portion of it to a third party;
• Use the App for any unlawful activity or any activity that infringes the rights of others;
• Access the App or its backend services using any automated means, scripts, scrapers, or bots.

4. Accounts and Identity

The App currently does not require account registration; you can use most features without providing personal identifying information. If an account system is introduced in the future, you are responsible for safeguarding your credentials and bear any loss arising from your own disclosure.

5. User Content

5.1 "User Content" means audio, video, project files, and derivative works that you import, record, edit, or share through the App.

5.2 Rights and responsibilities

• You represent and warrant that you hold the full copyright in your User Content or have obtained all necessary lawful authorization, and that your processing or sharing of User Content does not infringe any third party's rights (including copyright, neighboring rights, rights of publicity, privacy, personal-information rights, or trade secrets).
• You shall not use the App to process, generate, or disseminate any content that violates applicable laws or regulations; harms national or public interests; promotes terrorism, extremism, ethnic hatred, or discrimination; contains obscenity, pornography, or graphic violence; incites or teaches criminal activity; spreads disinformation; or infringes the lawful rights of others.
• You are solely responsible for all legal consequences (including administrative penalties, civil liability, and criminal liability) arising from your User Content.

5.3 By default, User Content is stored only in the App's local sandbox. We do not proactively read, analyze, share, or publicize your User Content. Only the AI Vocal Separation feature uploads the audio segment you explicitly select, and the segment is erased server-side immediately after processing.

6. Intellectual Property

6.1 All intellectual property in the App (including without limitation copyrights, trademarks, patents, trade secrets, and other proprietary rights) is owned by us or our licensors. Except with our prior written authorization, you may not use any of the App's trademarks, logos, interface design, copy, icons, fonts, sounds, or other elements.

6.2 The App incorporates open-source components (such as FFmpeg, SnapKit, Realm, SDWebImage, Lottie, MatomoTracker, among others) under their respective open-source licenses. The corresponding license notices are available in the "About" page of the App or on this website.

6.3 You retain all intellectual property rights in the User Content you create through the App.

7. Availability and Changes

7.1 Certain features depend on third-party platforms (such as Apple iCloud, Cloudflare, and Replicate). Their availability may be affected by network conditions, third-party status, applicable laws, or force majeure. We make no guarantee of uninterrupted, absolute, or error-free service.

7.2 We may add, modify, reduce, or suspend features of the App as operationally needed. Material changes affecting your core rights will be announced in advance through the App or this website.

7.3 We may carry out maintenance, upgrades, or migrations as needed. You acknowledge that brief service interruptions may occur in such cases.

8. Paid Content and Subscriptions

8.1 The App may offer one-time in-app purchases or recurring subscriptions. All payments are handled by the Apple App Store. We do not receive, store, or access your payment credentials (including card numbers or your Apple ID password).

8.2 You can review, manage, or cancel subscriptions in iOS Settings → your Apple ID → Subscriptions. Refunds are governed by the Apple App Store refund policy.

8.3 Specific pricing, renewal terms, and trial information are presented to you by the App Store at the time of purchase and prevail over any other description.

9. Disclaimers and Limitation of Liability

9.2 To the maximum extent permitted by applicable law, we are not liable for any direct, indirect, incidental, special, punitive, or consequential damages (including loss of data, revenue, goodwill, or hardware damage) arising out of or in connection with your use of, or inability to use, the App, whether based on contract, tort (including negligence), strict liability, or any other legal theory.

9.3 We are not liable for failures or interruptions caused by force majeure (including without limitation natural disasters, war, strikes, government action, backbone-network outages, computer viruses, or hacking). We will make reasonable efforts to restore service.

10. Termination

10.1 You may terminate this agreement at any time by uninstalling the App. Uninstalling will also remove all local data inside the App's sandbox; please back up anything you wish to keep beforehand.

12. Governing Law and Dispute Resolution

12.1 These Terms are governed by the laws of mainland China (excluding conflict-of-laws rules), regardless of where you access the App.
