What we store. Your study progress (flashcard schedule, quiz history) is stored only in your own browser using localStorage. It never leaves your device and we cannot see it. We do not require accounts and do not collect names, emails, or personal information.

Cookies. A single cookie remembers your language choice. If advertising is enabled, Google AdSense and its partners may set cookies to serve ads; you can opt out of personalized advertising at adssettings.google.com. Analytics, if enabled, uses aggregated, non-identifying measurements.

Third parties. Fonts are served by Google Fonts. Ads, when present, are served by Google AdSense under Google's own privacy policy.

Your choices. Clearing your browser storage removes all study data. Contact us via the Contact page with any privacy question.
