Essential vs optional

Essential storage is needed for the service to work: signing in, resuming a lesson and paying. Preference storage only remembers choices you have made on this device. Analytics is optional to the service: blocking it does not reduce any functionality.

Managing cookies

You can clear or block cookies and site data in your browser settings, and most browsers and content blockers can block Google Analytics specifically. Blocking essential storage will prevent you from signing in or resuming lessons.
