No accounts. You never sign in or give your name to this site.
Your progress stays on your device. Scores, settings, the name on your report and your teacher's email address are saved only in this browser (local storage). Clearing your browser data or choosing "Clear my progress" removes them.
Reports go only where you send them. "Email to my teacher" opens your own email with the report filled in; nothing is sent until you press Send.
Visit counts and ads. If this site shows ads or counts visits, it will use only non-personalized, child-appropriate settings, and this page will say which services are used.
