Necessary storage
Sign-in cookies, security/bot protection and browser storage used for preferences or notification dismissal support the service. They are distinct from optional analytics and advertising. Disabling all storage may prevent sign-in or stop preferences being remembered. Third-party payment or Google sign-in pages have their own storage and privacy notices.
Optional website tracking
Google Analytics, Google Ads conversion measurement, Meta Pixel and Vercel Analytics load only after the website tracking choice is accepted. The current banner offers analytics and advertising together; acceptance also declares the visitor is 18 or older. It is not verified age evidence or parental consent. Under-18 visitors should decline. The native Android app does not include these website advertising trackers.
Refuse or withdraw
You can decline without losing access to learning tools. The browser stores the choice for 180 days, unless you clear it or use Cookie Settings. Cookie Settings clears the stored choice and reloads the page with optional tracking disabled; choose Decline to keep it off. Blocking new tracking does not erase data already received by a provider. You can also use browser and provider deletion/opt-out controls, or contact us for a privacy request.
Cookie preference is local to that browser; account marketing preferences are separate and available in account settings.
