Cookie Policy

Cookies and browser storage (such as localStorage) are small pieces of information saved in your browser. We use both.

Sign-in: keeps you signed in and secures your session.

Preferences: remembers things like whether the app's side menu is open, lessons you've dismissed, and where to return after you sign in.

Without these, signing in and parts of the app won't work.

Google Analytics (cookies such as _ga) counts visits and how people find and use our site.

Microsoft Clarity (cookies such as _clck and _clsk) shows how pages are used, including session replays and heatmaps, to help us fix confusing pages.

These stay off until you choose "Allow analytics" in the cookie notice. If you choose "No thanks", they are not loaded. Your choice is saved in your browser.

Our text fonts are loaded from Google Fonts, which means your browser contacts Google when pages load.

You can change your analytics choice at any time with the "Cookie settings" link at the bottom of every public page. You can also block or delete cookies in your browser settings. Blocking essential cookies will stop sign-in working.
