Privacy

DRAFT: not final. This notice will be reviewed before the site launches.

Students

Students do not create accounts and never enter names, emails or passwords.
We do not collect personal information from students.
Lesson progress and the class code are saved only in the browser on the student's device (local storage). You can clear them by clearing the browser's site data.
Class codes identify a teacher's class, not a student.

No ads, no analytics, no tracking pixels and no third-party cookies.
Like any website, our hosting provider processes standard request data (such as IP address) to deliver pages and protect against abuse.
To stop people guessing class codes, wrong codes are counted per network using a scrambled (hashed) form of the address. The count is deleted automatically after 10 minutes.
A few lessons load web fonts from Google Fonts, which receives the standard request data needed to send the font.

Purchases are handled by our payment provider. We receive the license key and the purchase email needed to confirm the purchase and support refunds.
We store a fingerprint (hash) of the license key with the class it unlocked.

A contact form is coming soon.
