Privacy policy

Short version: the practice test runs entirely in your browser, and your answers never leave your device.

What we store

Your practice scores are kept in your own browser's local storage so the site can show your best result. They are not transmitted to us or to anyone else, they are not linked to your name or email, and clearing your browser data deletes them permanently.

What we collect

We do not ask you to create an account, and we do not run a contact form on this site. If you email us, we use your address only to answer you.

Access logs and third parties

Our hosting provider records ordinary server access logs, which may include IP addresses and browser information, for security and reliability. Should we later add analytics or advertising, this page will be updated to name the service and describe what it collects before it goes live.

External links

This site links to police and government pages. Those sites have their own privacy policies, which we do not control.
