LUER User Agreement

Last updated: April 2026

Welcome to LUER (the “App”). Please read this Agreement carefully before using the App. By downloading, registering, signing in, or using the App, you agree to be bound by this Agreement. This Agreement works together with our Privacy Policy.

1. Description of Services

LUER is an iOS app for check-in and related social features, including but not limited to:

• Check-in & records: daily check-in status (e.g., Yes/No), streaks, endurance, energy, and related statistics;
• Friends: friend relationships, requests, and interactions (e.g., likes, titles, profile card backgrounds);
• Dynamics (user-generated content): text posts, comments, and likes; feeds such as “Recommended” and “My friends”;
• Official mail: in-app messages from the operator, if available;
• Widgets: optional system widgets showing check-in summaries using on-device shared storage as designed;
• Tools in Settings: e.g., image utilities, document scanning, PDF tools—subject to what the App actually provides.

We may adjust features as the product evolves. Material changes will be communicated in the App or by other reasonable means.

2. Registration, Sign-In, and Security

• You must register as guided and ensure your information is truthful and accurate;
• Username length is typically 6–20 characters (letters, numbers, underscore—subject to in-app validation). Password: at least 8 characters, letters and numbers only (subject to in-app validation);
• You may use Sign in with Apple or other methods offered in the App. The number of LUER accounts that may be bound to a single Apple ID is subject to in-app rules and prompts;
• You are responsible for safeguarding credentials and for all activity under your account.

3. User Conduct

• Do not use the App for illegal activity or to violate others’ rights;
• Do not post obscene, violent, hateful, fraudulent, infringing, harassing, or otherwise prohibited content in display names, posts, or comments;
• Do not disrupt the App, servers, or other users—e.g., abusive automation or scraping;
• The App may block submissions that hit profanity or policy filters; further enforcement may apply.

4. User-Generated Content (UGC) and License

You are responsible for content you post in Dynamics, comments, and similar features. You represent that you have the rights or permission to post it.

To operate the App, display content, and maintain safety, you grant us a worldwide, non-exclusive, royalty-free, sublicensable license to host, copy, display, and distribute your UGC in the App and related services, and to use it as reasonably necessary to comply with law, enforce this Agreement, handle reports, and protect security.

Author display names in posts may be snapshots at publish time; older posts may not reflect nickname changes.

5. Reporting, Review, and Enforcement

You may report inappropriate display names in friend-related features and report posts or comments in Dynamics. We will review reports and may warn, delete content, restrict features, or take account-level action.

Dynamics reports: confirmed violations may result in removal of the reported post. To verify reports, information may include the post’s unique ID (momentId), the full post text (or legacy preview fields), the reported user’s username and UID, report type, description, and timestamp. The App may limit repeated reports of the same post within a short window to reduce abuse.

Comment reporting and deletion follow in-app rules; post authors or comment authors may be able to delete comments as implemented.

6. Privacy, Visibility, and Blocking

Privacy settings may control visibility of check-ins, Dynamics, friend requests, and more. Blocking may limit discovery and how posts appear in feeds. See the Privacy Policy and in-app descriptions.

7. Virtual Items and In-App Purchases

The App may offer virtual items (e.g., energy/endurance mechanics, titles, backgrounds) and Apple In-App Purchases. Scope, duration, and transferability follow in-app text and Apple policies. Unless required by law, completed IAP transactions are generally non-refundable; use Apple’s “Report a Problem” flow where applicable.

8. Data, Backups, and Disclaimer

Data is stored in the cloud and on device. We use reasonable safeguards, but we are not liable for loss or leakage caused by force majeure, network issues, third-party outages, device loss, or your own conduct, to the extent permitted by law.

9. Account Deletion

You may delete your account in the App after identity verification. We will delete or anonymize account data as described in the Privacy Policy. We do not guarantee removal of every historical UGC item or related record—actual scope follows server policy at the time. Deletion may be irreversible.

10. Changes to This Agreement

We may update this Agreement. Updates will be posted or prompted in the App. Continued use after the effective date means acceptance. If you disagree, stop using the App and delete your account.

11. Governing Law and Disputes

For purposes of this Agreement, this Agreement is governed by the laws of mainland China. Disputes should first be resolved amicably; if that fails, either party may submit the dispute to a competent court.

12. Contact

For questions about this Agreement, contact us via Help & Support in the App or other developer channels you may have.
