If you make quizzes
We store your email (for login), your quiz definitions, your API keys (hashed — we can't read them back), and the responses your quizzes collect. Payments are handled by Stripe; we never see card numbers. When you connect an AI assistant, we store an OAuth authorization linking that client to your account and issue it short-lived access tokens — disconnect the client and the tokens stop working.
If you answer a quiz
We store the answers you type, when you started and finished, and the page you came from. We do not store your IP address with your response, and we don't set tracking cookies on quiz pages — a random token in your browser's local storage lets you resume where you left off, and that's it. Your answers belong to the person who made the quiz; contact them for changes. If a quiz asks for something you don't want to share, don't — and you can report abusive quizzes from the link at the bottom of any quiz page.
Where data lives
Hosting on Vercel, database on Supabase (Postgres), both in the US. Free-plan responses are kept 90 days; paid plans keep them until you delete them. Deleted quizzes and their responses are purged within 30 days; expired sandbox quizzes are purged within days.
Removal & questions
Email abuse@quizgen.dev to report a quiz or request deletion of your data. We don't sell data to anyone.
