Manage privacy preferences

Keeps you signed in, protects the forms you submit, and remembers this very choice. The app cannot work without these, so they cannot be switched off.

Analytics

Lets us count visits and see which lessons people finish or abandon, so we can fix the ones that are not working. Nothing here is used to identify you.

Aggregated usage measurement

Preferences

Remembers choices that are not needed to sign in, such as your colour theme and app language, so the app looks the way you left it.

Theme, colour palette, chrome language

Advertising

Allows advertising, including ads chosen based on your interests, and the measurement that goes with it. Turning this off does not remove ads that are not personalised.
