If you play without signing in, your progress (XP, streaks, answered questions, scheduling data) is stored only in your browser via localStorage. Nothing is sent to our servers. If you clear your browser data, your progress is gone — sign in to preserve it.

We use Supabase for authentication. If you sign in:
- We store your email address (for login).
- We store your progress JSON (XP, streaks, SRS schedule, per-case scores).
- We do not share or sell this data. Ever.
- You can delete your account and all data at any time by emailing hello@biostatquest.app.
