Privacy

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 our database provider. Lessons and audio are generated by AI infrastructure providers; only your lesson settings (language, level, topics and words to practise) are sent to them to create each lesson. Lessons are AI-generated and may contain errors.

We use privacy-friendly, cookieless analytics to count visits and see which pages people find useful. No cookies are set for this, nothing follows you across other sites, and no personal profiles are built.

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.
