Privacy Policy

What we collect
If you create an account, we store your first name, email address, and your study activity (which cards you reviewed, the option you selected, and whether it was correct). If you use the app as a guest, that activity stays on your device in your browser's local storage.
How we use it
We use this data only to keep your place in the deck, show your progress dashboard, and let you sign in across devices. We do not sell your data or use it for advertising.
Text-to-speech and translation
Read-aloud uses your browser's built-in speech engine. When you pick a language other than English, the question and answer text is sent to a translation service to be translated. No account details are included in those requests.
Your choices
You can study without an account, clear on-device progress by clearing your browser storage, or ask us to delete your account data at any time.
