Last updated: 20 October 2026
What we collect
Your phone number, which you use to sign in with a one-time code, the profile details you add, your learning progress and scores, and your orders and library. We also keep basic technical logs to keep the service secure.
Why we use it
To sign you in, to give you access to what you have unlocked or bought, to save your progress, to process payments and to answer your questions.
Who sees it
Your information is not sold. It is shared only with the providers that run the service for us, such as SMS delivery and payment, and only as much as they need.
How long we keep it
We keep your data while your account exists. When you delete your account, we remove your personal data, keeping only what the law or a payment record requires, for as long as it requires.
Your choices
You can update your profile and delete your account from within the app. For any other request about your data, write to us from the contact page.
Cookies
We use a small number of cookies that keep you signed in and remember your basket. We do not use advertising cookies.
