Privacy Policy
Zhiming (“we”) cares about your privacy. This policy explains what information we collect when you use the Zhiming website and app (the “Service”), how we use it, who we share it with, and the rights you have. If this English version differs from the Simplified Chinese version, the Chinese version prevails.
1. Information we collect
| Category | What and why |
|---|---|
| Account information | Your email address and password (we store only a hash and can never see the original). If you sign in with Google, we receive your email address and its verification status from Google. Used to create and identify your account. |
| Birth information | The name, gender, date and time of birth, and place of birth you enter. Used to build your chart and generate readings and outlooks. Birth information is sensitive personal information, and we use it only to provide the Service to you. |
| Content you create | Questions and hexagrams when you cast, your journal entries and verification results, and your conversations with Ask AI. Used to generate readings, keep your records, and let later conversations build on earlier ones. |
| Technical information | Access logs kept by our servers for security and troubleshooting (such as IP address and request time). Your browser’s local storage keeps a login token so you stay signed in. |
We don’t collect your contacts, precise location or anything unrelated to the Service, and we don’t use third-party advertising trackers.
When you call our chart tools through the MCP service, no account is needed. We don’t keep the birth information, questions or hexagrams you submit — they are discarded once computed — and only keep the access logs described above.
2. How we use information
- To provide charts, readings, outlooks, Liu Yao interpretations, Ask AI and the journal;
- To send verification-code emails for sign-in or password reset;
- To keep accounts secure, for example by rate-limiting codes and temporarily locking an account after repeated wrong passwords;
- To troubleshoot problems and improve the Service.
We don’t sell your personal information or use it for marketing unrelated to the Service.
3. AI readings and third-party services
Chart readings, outlooks, Liu Yao interpretations and Ask AI are generated by large language models. To generate them, we send your chart data, a necessary summary of your birth information and your questions to a third-party model provider (currently Google Gemini, via an API provider). We never send your email, password or other account details.
The Service also uses the following third parties, which handle data under their own privacy policies:
- Google Sign-In: only if you choose to sign in with Google;
- Email delivery service: to deliver verification-code emails;
- Google Fonts: your browser requests web fonts from Google;
- Cloud hosting provider: hosts our servers and database.
Apart from the cases above and where required by law, we don’t disclose your personal information to any third party.
4. Storage and retention
- Your information is stored on our cloud servers and protected by access control, encryption in transit, password hashing and similar measures;
- Sign-in codes are kept in memory for 5 minutes only;
- Your account, charts, records and conversations are kept for as long as your account exists, and are deleted or anonymized within 30 days after the account is closed, unless the law requires otherwise.
5. Your rights
- Access and correction: you can view and edit your profile and birth information in the app;
- Deletion: you can delete charts and journal entries in the app;
- Account closure: you can ask us to close your account and delete all your data using the contact below; we’ll handle it within 15 business days after verifying your identity;
- Export and withdrawing consent: contact us if you want a copy of your data or wish to withdraw consent to any processing.
6. Minors
The Service is intended for adults. If you are under 18, please use it with the consent and guidance of a parent or guardian. We don’t knowingly collect personal information from children under 14 and will delete it promptly if we find any.
7. Changes to this policy
We may update this policy from time to time. Significant changes will be clearly announced on the website or in the app; continuing to use the Service after an update means you accept the updated policy.
8. Contact us
If you have any questions, comments or requests about this policy or your personal information, email [email protected].
