Privacy Policy

Last updated: July 2026

This Policy explains how Diandian Studio collects, uses, stores, and protects your personal information. We process your information only to the extent necessary to provide the service and meet legal obligations.

1. Information We Collect

Account data: email or phone number, nickname, password (encrypted), and avatar provided at registration.

Identity data: to meet regulatory requirements, we collect your legal name and ID number before you use creation and publishing features.

Usage data: content you create, upload, and publish, plus viewing, liking, commenting, and sharing activity, used to provide and improve the service.

2. How We Use Information

For login and account security, identity verification, content review, operations, troubleshooting, and compliance required by law.

We do not use your personal information for unrelated purposes; if a purpose changes, we will obtain your consent again.

3. Special Protection of Identity Data

Your ID number is stored encrypted with AES-256-GCM. No staff member can view the full number; verification is done via encrypted comparison only.

We use an irreversible hash of the ID number to prevent duplicate bindings; the original number cannot be derived from it.

4. Sharing

We do not share your personal information with third parties except: with your explicit consent; to comply with lawful requests from regulators or courts; or to initiate encrypted verification requests to licensed verification providers (no plaintext ID number beyond what is required).

5. Storage and Deletion

Data is stored on servers in the People's Republic of China. After account deletion, we will delete or anonymize your personal information once statutory retention periods expire.

6. Your Rights

You may view and correct your account information, and request account deletion. Verified identity data generally cannot be changed while the account is active; contact support if necessary.

7. Cookies

We use strictly necessary cookies to maintain login and security sessions, not for cross-site tracking.

8. Minors

The Platform is intended for adult creators. Users under 18 should read this Policy with a guardian and use the service with their consent.

9. Updates and Contact

Updates to this Policy will be posted on the site. For questions, contact us through the in-product feedback channel.
