Privacy Policy

We collect only what we need to cast and persist your Zi Wei Dou Shu chart: your email address (for sign-in), your name (if you provide it), your date and time of birth, your birthplace (city, country, coordinates, timezone), and your gender. We also collect payment metadata from Lemon Squeezy (our payment processor) — never your card number.

We use cookies for sign-in and to remember in-progress chart inputs. PostHog records anonymous usage analytics (page views, button clicks). We don't sell or share your personal data with advertisers.

Your birth data is used to compute your chart and to generate the AI-narrated interpretations you read. The interpretations are passed through one of our configured LLM providers (Anthropic, Kimi, or MiniMax). We do not allow the providers to train on your data.

Account data and charts are stored in Supabase (PostgreSQL, us-east-1). Generated reports are stored alongside the chart they came from. Payment records are held by Lemon Squeezy (our Merchant of Record). Email delivery is handled by Resend.

You can export all of your data at any time from /account/data. You can delete your account from the same page — this removes your charts, reports, and personal data permanently. We retain anonymous order records (no identifying data) for tax compliance.
