What we store: your books, ratings, reviews, reading log, avatar and settings. As a guest it lives only on this device. Signed in, it also syncs to our database (Supabase) so your shelf follows you across devices.
Sign-in: we use your email only to send a magic link and keep your account — no password is ever stored.
Public shelf: private by default. Going public is opt-in, you choose what it shows, and you can switch it off anytime.
Analytics: anonymous usage counters only (e.g. "a book was added") with a random session id — no name, email, IP address or book titles.
Feedback: if you send feedback while signed in, your email is included so we can reply (delivered via Web3Forms).
Your rights: in Account you can download all your data (JSON) or delete your account — deletion permanently erases your profile, books, reviews and reading log.
Questions or requests: use the 💬 feedback button and we'll get back to you.
