Privacy policy

We collect as little as possible, encrypt what we must store, and delete it on schedule. This page states plainly what happens to your data.

What we store

Your birth details, the question you asked, the engine output and the generated reading. All of these are encrypted before they reach the database.

How it is protected

Personal fields are encrypted with AES-256-GCM at the application layer. The database holds ciphertext only — operators see record counts, not contents.

How long we keep it

We keep your records for 12 months from creation. After that they are deleted automatically. You can delete any record yourself at any time.

Deletion and access

You may delete individual records or your whole account at any time. Deletion removes the encrypted rows; encrypted backups expire within the same 12-month window.

Third parties

Payments are handled by Stripe. Infrastructure is provided by Vercel and Supabase. We do not sell your data.

For any question about your data, email us at zheshigansha@gmail.com (backup: 121179420@qq.com). We will never ask for your password.
