Privacy Policy

Draft: placeholder text pending legal review (TODO_VERIFY). The effective date, controller details and governing law will be set in the final version.

1. What we collect

• The free BaZi calculator page. The birth date, time and city you type stay in your browser. They are not sent to our servers.
• When you use the app and sign in. Your email address (for sign-in), any birth details and name you choose to save, preferences, subscription and payment status, and your conversations with Xiao Wu.
• Technical information. The minimum logs needed to keep the service secure and stable, such as request time and error messages. Birth details are never written to logs.

2. How birth details are stored

Birth date, time and place are sensitive. If you choose to save a profile, they are sent over an encrypted connection and stored on our servers with field-level encryption. You can also turn on local-only mode, in which case the raw details never leave your device.

3. How AI uses your information

The AI assistant receives only “feature facts” produced by the chart engine, such as your element balance and season, never your birth date, time or city. AI-generated content is always labeled.

4. What we do not do

• We do not sell your personal information.
• We do not serve third-party ads.
• We do not share your birth details with other users. A bond shares element traits only after the other person consents.

5. Your rights

In the app, under Settings › Privacy, you can export your data or delete your account and profiles at any time. Retention periods and the exact deletion process: TODO_VERIFY.

6. Age

This service is for ages 18 and over.

7. Cookies and storage

The site uses cookies and local storage only for essentials such as sign-in state, language and display preferences. The itemized list: TODO_VERIFY.

8. Changes and contact

We will tell you about material changes. Contact details and the channel for data-subject requests: TODO_VERIFY.
