LitBook stores the minimum needed to run the app: your account (an anonymous ID, or your email if you sign in) and your lesson history (the passages, questions, your answers and scores). That's it — no ads, no selling data, no tracking across other sites.

Data is stored with Supabase (our database provider). Lesson text is generated by Anthropic's Claude; your lesson settings are sent to Anthropic to create each lesson. Lessons are AI-generated and may contain errors.

Guest sessions live in your browser — clearing your cookies removes access to that history. To delete your account and data, or for any question, contact us and we'll handle it.
