What is stored

Without an account, lesson progress, typed answers, handwriting and speaking recordings stay in this browser. With an account, lesson completion, quiz answers, review scheduling, bookmarks and typed practice can also be stored in the course database so they can sync across your devices.

What is not uploaded

Handwriting images and speaking recordings remain on the device unless a future feature asks for separate, explicit permission. The course does not include advertising trackers.

Account data

The authentication provider stores your email address, an encrypted password verifier and normal security logs. Row Level Security restricts each signed-in learner to their own learning record.

Your choices

You can export your learning data, delete synced learning data, sign out, reset local data, or permanently delete your account from Learning settings.
