Everything you do in the reader — highlights, notes, bookmarks, folders, the chapter you stopped in, your reading plan, and every setting — is written to your own browser's storage. It does not leave the device unless you turn on sync.
Clearing this site's data in your browser erases all of it, and there is no copy anywhere else. That is the point of it, and also the risk: it is why sync, the export file and the transfer link exist.
The app mirrors those same saved items to your own iCloud account, through Apple's key-value storage, so they follow you between your own Apple devices. That needs no account here and nothing reaches us. What Apple does with data in your iCloud is covered by Apple's privacy policy rather than this one, and turning iCloud off for the app in iOS Settings stops it.
Sync is off until you ask for it, and the whole reader works without it.
When you do turn it on, two things are kept on a server:
They are held in a database run by Supabase, Inc. on our behalf, and the sign-in codes are delivered by Resend, Inc. Every row is locked to the account that wrote it by the database itself, so no other signed-in reader can reach yours.
Your notes are not read, analysed, mined, or shared with anyone.
Settings, then Sync, then Delete account. That removes the account and everything stored with it at once. Copies may survive for a short time in the database provider's routine backups, and then they are gone too.
Turning sync off instead leaves everything on the device exactly where it is and only stops the copying; the server's copy stays until you delete the account.
The Bright edition is written for children. It gathers nothing extra, and nothing at all unless sync is switched on. Accounts are not knowingly created for children under 13, and none is needed: every word of the reader is open without one.
If anything here changes in a way that matters, the date under the title changes with it.
