Study progress

Your progress is stored in this browser on this device using IndexedDB. Accounts are optional, and you can use the full app as a guest. If you clear this browser's site data or use another browser or device, that local progress may not be available. If you sign in, your progress is also saved to your account so it is available on your other devices (see below). Guests never send progress anywhere.

Progress backup files are created and selected on your device. They stay on your device unless you choose to move or share them yourself.

Optional Google account

When you sign in with Google, Google shares your name, email address and profile picture with our authentication provider, Supabase, in its US region. Supabase stores them with your account. We use this information only to sign you in and to sync your study progress.

While you are signed in, your devices copy this study progress to your account: practice answers, mock exam attempts and their answers, your flashcard schedule, and your test date and mock timer choice. Theme, text size and motion settings stay on each device. This progress is stored with Supabase in its US region, together with your account, and is not shared with anyone else. It is deleted when you delete your account. You can also delete it without deleting your account: in Settings, choose Delete all my progress and keep the box for your account ticked.

You can delete your account at any time from Account. Deletion removes the account and any data saved to it. You can also choose to remove progress from this device. Accounts are for people 13 and older.

Site operations

The app does not use analytics, advertising trackers, or third-party tracking scripts. The static hosting provider may process standard request logs, such as the requested URL, time, and technical connection data, to serve and secure the site.

Feedback and optional tips

If you send feedback, we collect your message, optional email address, question ID when reporting a question, page path, and app version. Feedback is stored with Supabase, our database provider. We use it only to reply when you request a reply and to improve the app. To ask us to delete your feedback, use the same form and describe which message to remove.

Optional tips are processed by Stripe on Stripe's own checkout page. We never see your card details. Stripe's privacy practices apply when you visit its checkout page.
