When you create an account, we collect your email address. We store your shelf, journal entries, letters, and kindred pairings on Supabase (hosted on AWS) so they follow you across devices.
Your age and reading pace never leave your phone. They live in local storage on the device, power the mortality math, and are never sent to our servers.
A few processors do the unglamorous work. Sentry receives crash and error reports; we scrub your email and IP address before anything reaches it (in our beforeSend hook). On iOS, subscriptions run through Apple and RevenueCat, which see purchase and subscription identifiers tied to your Apple ID. On the web, subscription billing runs through Stripe. We don't hand any of these companies your shelf or your journal.
Your data is used solely to power Last Book Shelf features: your personal shelf, reading statistics, kindred matching, and recommendations. We do not sell your data to third parties.
Data is stored securely via Supabase (hosted on AWS). Local data is stored on your device via browser storage.
You can request deletion of your account and all associated data at any time by contacting us.
