Privacy notice

Last updated 26 October 2026

We keep as little about you as possible. There are no ads, no tracking and no selling of data.

If you don’t create an account

We don’t collect anything about you. Your progress, answers and settings are saved only in your own browser (using “local storage”) and never leave your device. Clearing your browser data deletes them.

If you create an account

We keep:

• Your first name and email address, to sign you in and greet you.
• A secure version of your password. We never see or store your actual password.
• Your study progress and settings, such as answers, scores, notes and your chosen theme, so they follow you to other devices.

If you sign in with Google, Google shares your name and email address with us. We don’t get access to anything else in your Google account.

What we use it for

• To sign you in, keep your progress in sync, and send emails you ask for, such as confirming your email or resetting your password.
• Nothing else. We don’t send marketing emails, show ads, or sell or share your information with anyone for their own use.

Where it is stored

Account information is stored with our database and sign-in provider, Supabase, which keeps it on secure servers. Fonts are loaded from Google Fonts, which may see your device’s IP address when the page loads.

How long we keep it

We keep your account until you ask us to delete it. If an account is unused for three years, we may delete it.

Your choices

• See or correct your information: contact us and we’ll help.
• Delete your account and everything in it: contact us from the email address on your account, and we’ll delete it within 30 days.
• Sign out: signing out removes your progress from that device. It stays safe in your account.

Students under 18

The site is made for secondary school students. If you are under 13, please ask a parent or guardian before creating an account. Parents and guardians can contact us at any time to see or delete their child’s information.

Changes

If we change this notice, we will update the date at the top of this page.
