What we collect. (1) Data you submit when you create an account (name, email, hashed password). (2) Birth data you enter into calculators — processed to produce your result and stored only in your private "My Calculations" history if you tick "save". (3) Basic server logs (IP, request path) for security and debugging, never matched to content you submit.
What we never do. We never sell personal data, never log passwords or session secrets, and never expose one user's saved calculations to another user or to the public.
Your rights. You can delete your saved calculations at any time from My Calculations and ask us to remove your account by emailing admin@fengshuicentral.com.
