Your learning, on your device.

Lesson completions, review schedules, and romanization preferences are stored in this browser’s localStorage. No account or cloud sync is used. Clearing browser data removes your progress. You can also reset it here.

Korean of the Day results, your streak, XP and badges are stored in this browser too. Text you type into the romanizer stays in your browser. Share buttons open X or LINE with the page link and your score grid only.

Listening uses your browser’s speech synthesis service. Depending on the device and selected voice, text may be processed by its speech provider. No microphone or pronunciation recording is used.

No advertising or analytics scripts are active in this edition. Fonts are requested from Google Fonts, which receives the network information needed to serve them.
