Cookie Policy

We store one cookie, to keep you signed in, plus a few settings saved by your own browser so that features behave the way you left them. We do not use advertising cookies, we do not run analytics or tracking tools, and nothing here is shared with advertisers or data brokers.

Cookies are small text files a website stores on your device so it can recognise you between requests — for example, to know you are still signed in. Browsers also offer “local storage”, which works similarly but stays on your device and is never sent to us automatically.

• Session cookie — created when you sign in and removed when you sign out. It identifies your session so the platform knows who you are on each request, and it is what protects your account. This is strictly necessary: without it you cannot stay signed in.

These are saved by your browser on your own device. They are not transmitted to us on their own and are not used to identify or profile you.

• Your answers and your place in a test you are currently taking — a safety net so that a crashed tab, a closed browser or a dropped connection during an exam does not lose the last few minutes of your work.
• Whether you switched exam-hall sounds on or off in the test runner.
• Whether you have already dismissed the summary shown after a review session.

Clearing your browser data removes all of these. The only visible effect is that an in-progress test falls back to the last answers saved on our servers, and those two preferences return to their defaults.

We do not use any. There is no Google Analytics, no advertising pixel, no session recording and no cross-site tracking on this platform. If that changes, we will update this page and ask for your consent before any such technology is enabled.

A small number of services are loaded to make the platform work, and they may set their own cookies when their content is used:

• Our video provider, when you play a protected course or lecture video.
• Google Fonts, which serves the typefaces used across the site.
• Google Sign-In, only if you choose to sign in with a Google account.

These are governed by those providers' own privacy policies. We do not use them for advertising or profiling.

Every major browser lets you view, block or delete cookies and local storage in its settings. Because the only cookie we set is the one that signs you in, blocking it will sign you out and prevent you from accessing your courses and tests.

We will update this page if what we store changes, with a revised “last updated” date above.
