What this site stores

The quiz uses your browser's sessionStorage to keep the current five-question set, your answers, and a short history of recently played sets. This supports page-to-page progress, score display, and choosing another set. SessionStorage stays in your browser for the current browsing session and is normally cleared when that session ends. We do not use an account, database, or server-side quiz profile.
