Draft for v1 — not a final legal policy. Last updated October 2026.
What we store
- Account email and display name
- Password hash (argon2id — we never store your password in plain text)
- Lesson progress (step, status, optional quiz score)
- AI hint/explain usage metadata (lesson, model, token counts) when you use those features while logged in
- Session cookies (`access_token`, `refresh_token`) for login
What we do not do
We do not sell personal data. We do not run your lesson code on our servers. Anonymous visitors may keep a step index in browser `localStorage` only.
Cookies
