Effective for version 0.4.0
Privacy
The current build is a static, frontend-only application. It has no account system, database, analytics SDK, advertising script, form submission or server-side learner profile.
Data stored in your browser
The app uses localStorage for answer history, mastery, review dates, scores, streaks, personal records, accessibility preferences, skipped instruction choices and the most recent result. This data remains in the browser profile on the current device.
Data sent elsewhere
This build does not intentionally send learning activity to Language Hub or a third-party analytics service. Static hosting providers may still produce ordinary infrastructure logs outside the application; the site owner must disclose the deployed host’s actual practices before launch.
Export and deletion
Settings can export learning progress as JSON and import a compatible backup. The reset control removes app progress from localStorage. Browser site-data controls can also remove all locally stored settings and progress.
Advertising and donations
No advertising or donation integration is included in this release. If advertising, consent tooling or analytics is added later, this page and the deployed consent behaviour must be updated before those scripts are enabled.
Children and sensitive data
The app does not ask for a name, email, age, location, health information or payment information. Users should not place sensitive information in exported backup filenames or manually edited backup content.
