Plain-English summary of what data we hold, why, and the control you have over it.
Last reviewed: 9 July 2026
You can take practice tests without creating an account. When you do, your answers and progress are stored locally in your own browser (localStorage) on your device. They are not sent to us and we cannot see them.
A free account lets you save your results and track progress across devices. In that case we store the email you sign up with and your saved practice results. We do not sell your data, and we do not use your results for anything other than showing you your own progress.
We use privacy-respecting analytics to understand which pages are useful, in aggregate. This does not identify you personally.
You can access, export or delete your data at any time. Deleting your account removes your saved results. For local (no-account) practice, clearing your browser storage removes everything.

If this policy changes we will update the last-reviewed date above and, for material changes, note it on the site.
