SimpleQuiz keeps only what it needs to run quizzes and study sets. Here is all of it.

If you have an account

Your email address and how you sign in, so you can sign in again.
The quizzes and study sets you make, with their questions and the images you upload.
Results of the live games you host: the nicknames players chose and their answers. They are deleted 7 days after the game ends.
When you study while signed in: for each question, how often you answered it, how often correctly, and your last answer; the questions you starred; and your finished sessions. No other user can see them: the person who made a set never sees your progress.

Joining a live game needs only a nickname. It is kept with your answers as part of that game's results, which the host can see, and deleted 7 days after the game ends.
Study progress is kept only in your browser, not on our servers, until you sign in. Signing in moves it into your account.
To slow down people guessing game codes, failed join attempts are counted by a scrambled form of your IP address, never the address itself, and forgotten after a day.

Sign-in cookies, and your choice of theme and language.
For live games, a token that lets you rejoin after a dropped connection. For study sets, your progress and the sets you opened recently.
No advertising or tracking cookies, and no analytics.

Supabase stores the database, accounts and images; Vercel runs the website; Resend sends the sign-in emails. We don't sell data, and nothing is sent to AI services.
Anyone with a study set's link can open that set. Its owner can change the link at any time, and the old one stops working.

Signed in: Account → Delete my account removes your account and everything in it at once, including your images.
Study progress for one set: Statistics → Start over.
Without an account: clearing this site's data in your browser removes everything kept there.
