Cookie Policy

Last updated: July 2026

Strictly necessary cookies

• eto_session — keeps you signed in. Set only when you log in; expires after 30 days.
• theme — remembers your light/dark preference for one year.
• cookie_consent — records your cookie-banner choice for six months.

These are required for the site to function and cannot be switched off.

Analytics cookies (optional)

If you click "Accept all" on the cookie banner, we load Google Analytics with IP anonymisation to understand which topics help learners most. If you click "Reject all", Analytics never loads — the site works exactly the same.

Advertising cookies (future)

We may introduce Google AdSense advertising. If we do, advertising cookies will load only for visitors who have accepted them, and this page will be updated first.

Changing your choice

Clear the site's cookies in your browser and the consent banner will appear again on your next visit. See also our Privacy Policy.
