Quant Practice ("the site") is a free, non-commercial quant-interview practice tool. This page explains what data the site collects and how it's used. Last updated July 2026.
What we collect
- Sign-in via Google. When you sign in, Google shares your name, email address, and profile picture with the site through Supabase Auth. We don't receive or store your Google password.
- Drill activity. If you complete a drill (Mental Math, Market-Making, Probability & Stats), we store your score, timestamp, and basic session metadata (e.g. accuracy, average answer time) tied to your account, so your progress and stats can be shown back to you on your Profile page.
- Problem flags. If you flag a probability problem as incorrect or confusing, we store that flag against your account so it can be reviewed.
What we don't do
- We don't use any analytics, advertising, or tracking scripts.
- We don't sell, rent, or share your data with third parties.
- We don't email you outside of Google's own sign-in flow.
Where data lives
Account and drill data is stored in a Supabase (Postgres) database. Row-level security restricts each account to reading and writing only its own rows.
Your choices
You can sign out at any time from the navigation bar. To request deletion of your account and associated data, email the address below.
