Privacy Policy

To calculate your BaZi reading, we collect:

• Birth date, birth time, and gender (entered by you)
• Optional: name, birth place (for timezone precision)
• Anonymous usage analytics (page visits, no personal identifiers beyond IP)

Your birth data is used solely to:

• Calculate your Four Pillars chart and generate your AI reading
• Cache your reading so you can return to it (you can opt out by not saving)

We do not sell, rent, or share your data with third parties for marketing.

Your birth data is sent to DeepSeek (third-party AI provider) for chart interpretation. DeepSeek's API does not retain inputs beyond the immediate request window. We do not include your name, email, or any other identifier in the AI prompt.

Payments are processed by:

• USDT (TRC20) — on-chain transactions, no intermediary holds your data
• Gumroad — subject to Gumroad's own privacy policy. We only receive the order ID and payment confirmation; we never see your card details.

We use a self-hosted SQLite database for anonymous page-view analytics. No third-party tracking scripts (Google Analytics, Facebook Pixel, etc.) are loaded on this site.

Saved readings are kept indefinitely unless you request deletion. To delete your data, email us at the contact address below with your reading hash.

You have the right to:

• Access the data we hold about you (your reading history)
• Request deletion of your data
• Opt out of analytics (we respect Do-Not-Track headers)

For privacy questions or data deletion requests, contact us via the form on ourabout page.

We will post any changes on this page with an updated revision date. Material changes will be announced on our homepage.
