- Functional cookies remember something you did on the Website, such as your progress in a course.
- Analytics cookies measure how the Website is used. We only use them with your consent.
We do not use advertising or targeting cookies.

Analytics on the Website
- We use Google Analytics to understand how the Website is used.
- Analytics cookies are set only if you accept them.
- Until you choose, Google Analytics runs in a consent mode that does not store cookies. In this mode it can still receive basic signals without identifiers, such as that a page was viewed.
- Analytics cookies do not collect your name or contact details; they distinguish visitors with a randomly generated identifier.
- Google Analytics data is processed on Google's servers, including outside the UK.

Third-party content

These cookies are governed by the provider's own policies.

- You can change your choice at any time with the “Cookie settings” link at the bottom of every page. Withdrawing consent is as easy as giving it.
