Note: Analytical and advertising cookies are only set on our public pages for parents and schools, for signed-out visitors and school staff (and once when a payment is confirmed, to count the purchase). They are never set for students, in child mode, inside the signed-in app, or on the pages students use to join (Join, Gateway, Chess, Junior Guide). In the EEA, the UK and Switzerland they are only set after you accept cookies in the banner. Elsewhere they are set unless you decline in the cookie banner (where it is shown), turn on 'Opt Out of Non-Essential Data Sharing' or 'Do Not Sell My Personal Information' in Settings while signed in, or your browser sends Global Privacy Control. You can also block or delete cookies in your browser. Essential cookies cannot be disabled as they are required for the platform to function.
