Privacy policy

Last updated: 13 November 2026

The short version

There are no accounts, no sign-up forms, no advertising and no tracking scripts. Your study progress stays in your own browser.

What is stored in your browser

The site uses your browser's local storage and a service worker cache. Nothing in them is sent to us.

• Topics you mark as done, the last page you read, and where you stopped on each page.
• Test attempts in progress (answers and the end time), so a reload does not lose your work.
• Your test scores, so the tests page can show your best score.
• Items you tick on the study plan.
• Your light or dark theme choice.
• Copies of pages you have visited, so the site loads faster and works offline.
