Privacy

What we store: your username, a hashed password, the name you enter, your email if you give one, which team code you used, and your learning activity (nodes read, cards rated, questions answered, scratchpad text, feedback you send). We store when you last used the site.

What we do with it: show you your own progress; show a manager the progress of people who joined their team; send the daily question if you opted in (one email a day, unsubscribe in any email or in your settings); fix the course from your feedback.

What we do not do: sell or share the data, track you across other sites, or load third-party analytics. The site sets one session cookie needed to keep you logged in. Fonts are loaded from Google Fonts; that request shares your IP address with Google.

Deletion: email us from the address on your account and we delete the account and its activity within seven days.
