Privacy

Without an account

Your practice — every answer, every mock exam, your level — is stored in your browser on this device. It is not sent anywhere.

With an account

We store your email address, your password as a one-way hash (or the link to your Google account if you sign in with Google), your name, photo and the text on your profile if you add them, and your practice and mock exam results, so they are the same on every device. Each sign-in is recorded with its time and IP address; those records are deleted after 90 days.

Teachers

A teacher sees your practice only if you join their class with its code. They see your name (or email address if you have not set a name), photo, accuracy per drill, weak spots, practice per day and mock exam results. Leave the class on your profile page and they stop seeing it at once.

The waitlist and feedback

If you join the waitlist we keep your email address and, if you tell us, whether you are a student, teacher or parent, to write to you when eart opens fully. Feedback is kept with the page it was sent from; an email address is optional.

Analytics

We count visits and signed-in users with our own analytics. Signed-in users are counted by an internal account number, never by email address.

Deleting

You can delete all your practice from the progress page. To delete your account, write to us through the feedback form with an email address to reply to.
