Privacy notice

The short version: we keep the least we can, we don't sell it, and we don't track you.

What we keep about you

• Your first name, username and password. The password is stored scrambled, so nobody can read it, us included.
• Which subjects you picked, and how you rated each card. That's how the app decides what to show you next.
• If a parent links to your account, their email address and the link between you.

What we don't do

• No adverts, no selling or sharing your data, and no tracking or analytics cookies.
• The only cookie is the one that keeps you logged in.
• We don't ask for your email, your school, your location or your age (just that you're 13 or over).

Who can see your progress

Only you, a parent you've chosen to link, and the people running the site, if they need to fix a problem. A linked parent sees how much you've studied and how well you're doing. They don't see your answers. You can remove a parent link from your Parent access page whenever you like.

Where it's stored

On servers in London, with our hosting provider Fly.io.

Deleting your account

Ask us and we'll delete your account and all your study history. Under UK GDPR you also have the right to see the data we hold about you, and to correct it.
