Privacy policy

Short version: your data stays on your device. Progress, missed questions and Challenge Bank entries are stored in your browser's local storage only. We never see them.

We serve advertising (currently Google AdSense). Google and its partners may use cookies to personalize ads. You can opt out of personalized advertising at Google Ad Settings. We do not sell, share, or transmit your quiz data — there is no account system and no server-side storage of anything you do here.
