What we collect
- Account data. Your email address and OAuth profile (if you sign in with GitHub or Google) — used to identify your account.
- Performance data. Session results, ELO scores, card review history, and topic ratings — stored to power spaced repetition and personalised question selection.
- Code submissions. Code you write in coding drills is sent to Judge0 for execution and to Anthropic for AI feedback. It is not stored beyond what your session record contains.
- Usage data. Vercel and Supabase automatically log IP addresses and request metadata for security and infrastructure purposes. We do not control or access these logs directly.
