Choose Beginner, Intermediate or Advanced on the Map - every course can be started from its first stage. Each stage is a short lesson, bonus game or boss battle. You have three hearts per stage; clear it to earn stars and unlock the next one. Words you have learned appear in the Word Book, and the Review tab collects your mistakes.

The App uses your device's Korean text-to-speech voice. If none is installed, My Page shows a notice and listening questions are replaced with other questions. On iPhone and iPad, add a Korean voice under Settings → Accessibility → Spoken Content → Voices. On Android, open Settings → Text-to-speech output (often under Accessibility or System) and install Korean voice data for your engine. Menu names vary by OS version and manufacturer. Also check your media volume and that "Auto-play pronunciation" is on in My Page.

Sound effects follow your device's silent mode - on iPhone and iPad they are muted by the silent switch, and on Android they don't play in silent or vibrate mode. You can also turn them off and on in My Page → Sound effects.

Progress is stored only on your device. There is no account or cloud sync, and we keep no copy, so deleting the App erases your progress and we cannot restore it. Your device's own backup (iCloud Backup or Android backup) may bring it back when you restore a whole device, but this depends on your backup settings and is not guaranteed.

Use My Page → Settings → Reset progress to erase all stars, coins and words, or delete the App to remove all of its data. We do not hold any of your learning data.

There are no in-app purchases. Coins, hints, revive potions and Haru's outfits are earned by playing and cannot be bought with real money. The App shows rewarded video ads only when you choose to watch one for a bonus, such as opening a scene, doubling coins, a hint, saving your streak, doubling the daily chest or free coins. There are no banner ads or ads that start on their own, and you can play without watching any. If you paid for the App itself, payment and refund requests are handled by the store you bought it from - Apple (https://reportaproblem.apple.com) or Google Play (https://support.google.com/googleplay/answer/2479637).

In My Page → Settings, choose English or 日本語 as your helper language and turn "Show romanization" on or off. The App starts in Japanese if your device is set to Japanese, and in English otherwise. From the Platinum mastery rank onward, questions are shown without romanization.

No account is needed - there is no sign-up. Lessons work offline; an internet connection is needed only to watch optional ads for bonuses.
