Terms of Service

Welcome to 弦动! These terms are an agreement between you and Shanghai Zhuqu Technology Co., Ltd. ("we", "us") about your use of the App and related services. Please read them carefully, especially the limitation of liability and dispute resolution clauses in bold. By signing up for, signing in to or using the App, you confirm that you have read and agree to these terms.

1. Your account

• Without signing in, you can use the App's on-device features as a local guest. Cloud sync, sharing and score recognition require an account.
• You can sign up and sign in with an email address. 【待填写：如上线手机号、Apple 登录，在此补充（英文）】
• The information you provide must be true and accurate. As required by law, some features may require you to verify a phone number.
• Your account is for your personal use only and may not be transferred, lent or sold. Keep your sign-in credentials safe; you are responsible for losses caused by failing to do so.
• If you notice someone else using your account, notify us immediately using the contact details at the end of these terms.

2. Acceptable use

You must comply with the laws of the People's Republic of China when using the App, and must not use it to:

• Publish or spread illegal content, or infringe the intellectual property, privacy or other rights of others;
• Interfere with or disrupt the App, its servers or networks;
• Reverse engineer or decompile the App, or access the service with automated tools, without permission;
• Do anything else that violates the law or public order and good morals.

If you break these rules, we may issue a warning, restrict features, or suspend or terminate the service, depending on the circumstances.

3. Scores you upload and share

• Any score you upload by importing, recognizing, syncing or sharing must be a work you have the right to use (for example, licensed to you or in the public domain). You are responsible for any infringement arising from content you upload or share.
• Rights in the scores you upload remain with you or the original rights holders. We process this content only to provide storage, sync, recognition and sharing to you.
• If a rights holder believes content in the App infringes their rights, they can notify us using the contact details at the end of these terms, and we will handle it promptly according to law.
• Cloud storage and score recognition have usage limits, as shown in the App.

4. Personal information

How we collect, use, store and protect your personal information, and your rights, are described in our Privacy Policy.

5. Intellectual property

The intellectual property rights in the App and the software, interface designs, text, graphics and other content we provide belong to us or the relevant rights holders. No one may copy, modify, distribute or use them commercially without our written permission.

6. Changes, interruptions and termination

• The first version of the App is free and has no paid features. We may adjust the service as our business develops and will notify you in advance in an appropriate way.
• The service may be temporarily interrupted for maintenance, upgrades or force majeure. We will try to give advance notice and restore it as soon as possible.
• You may stop using the App and request account deletion at any time; see the Support page.

7. Limitation of liability

To the extent permitted by law, we are not liable for service interruptions or losses not caused by our fault, such as force majeure, network failures or problems with third-party services. We make reasonable efforts to keep the service stable and secure.

8. Minors

If you are under 18, please read these terms with your parent or guardian and use the App only with their consent.

9. Changes to these terms

We may update these terms from time to time. Updated terms will be published in the App and on this website, and we will notify you prominently of significant changes. If you do not agree with the updated terms, you may stop using the App and delete your account.

10. Governing law and disputes

These terms are governed by the laws of mainland China. Any dispute arising from these terms should first be resolved through friendly negotiation; if that fails, either party may bring a lawsuit before the competent people's court where Shanghai Zhuqu Technology Co., Ltd. is domiciled.
