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.

If you opt in, PostHog provides product analytics and privacy-masked session replay so we can understand where visitors abandon signup or lessons. Form inputs are masked in your browser before data is sent. Account recovery, settings, support, payment and admin pages are never recorded. We identify signed-in learners only by their internal account ID, not by email, and never record operator accounts. You can change this choice below at any time.

On the Contact Support page, if you choose to open live chat, our support provider Crisp uses a functional cookie to keep your conversation available between pages and visits. Crisp processes your messages, technical connection information such as your IP address, and any contact details you choose to share. The chat does not load and its cookie is not set until you open it.

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.

LitBook may send a limited learning reminder after an unfinished draft or a first completed lesson, or after an account is created but setup is left unfinished. These reminders can be turned off at any time from the email or Account Settings; account and security emails are unaffected.

We keep an email contact record for account operations and synchronize subscription status with Resend, our email provider. Product news and learning tips are promotional emails and are sent only when you explicitly opt in. This choice is separate from learning reminders, and can be changed in Account Settings or through the unsubscribe link in every marketing email.
