Questions about the app? Contact Denden Software.
Please include your app version, device model and a short description of the problem. Do not send passwords, payment details, private photos or your whole backup file.
1. Restore a purchase
Use Settings → Unlimited cards → Restore purchases with the Apple Account (iOS) or Google Play account (Android) used for the original purchase. Use the same store; purchases do not transfer between Apple and Google Play. This restores paid access, not your collection.
2. Can I learn with lyrics?
Add lyrics you wrote or have permission to use to My Lyrics in a song card. In Practice, expand Lyrics and choose Study lyrics, or open the song details. Pick a line containing Korean syllables to listen, build syllables and practice writing. This is free and uses no extra cards. Lyrics stay on your device and are included in personal backups. The app does not provide, search for or download lyrics.
3. Save your collection
Use Settings → Backup & restore before replacing or resetting your device. Keep the exported backup file somewhere you can find again.
4. Request an artist
In Search artists, choose “Missing an artist? Request one”. Send the artist or group name only.
5. Privacy questions
Contact us with enough detail to describe your request. We do not keep an app account or a device-to-request directory, so anonymous records may not be identifiable.
