Privacy Policy
Last updated 29 July 2026
What we collect, why, and what we don't do with it. We've kept the data we hold deliberately small.
Account: your email address, and your name if your sign-in provider shares it. That's what identifies your account and what any purchase is tied to.
Learning: which lessons you've completed, XP, streaks, quiz answers, and the notes you write.
Billing: handled by Stripe. We store a Stripe customer reference so we know which subscription is yours. We never receive your card number.
No advertising trackers, no third-party analytics pixels, no data brokers.
We don't sell your data. There is no version of this product where we do.
Your progress is currently stored in your browser. Clearing site data clears it.
Account and billing records are held by our auth and payment providers (Stripe) under their own security controls.
If you sign in with Google or Apple, we receive your email address and name from them so we can create your account. We don't get access to anything else in those accounts.
Apple's Hide My Email is supported — we only ever need a working address to reach you about your account.
We email you about your account: receipts, renewals, and material changes to these policies.
We won't add you to a marketing list without asking.
You can ask for a copy of your data, ask us to correct it, or ask us to delete your account and everything attached to it.
Email the address on the contact page and we'll action it within 30 days.
One essential cookie keeps you signed in. That's it — no tracking or advertising cookies.
