Information and purposes
The app reads selected audio and its title, artist, album and lyrics for music playback and listening practice. File information, playlists, bookmarks, playback positions, study and sound settings are stored on your device. The library uses audio-read permission. Device files can be played without Google sign-in. Original files are not modified or deleted.
Optional Google Drive and external services
If you choose Drive, you connect a Google Account and select the files to use. Requests needed for account authorization and playback are sent to Google, and selected media is read from Google. Account identifiers and email, selected-file information, lists and playback records may be stored on your device. The app has no feature that uploads media or usage records to an operator server and has no advertising. See the Google Privacy Policy for Google’s processing. The app’s use of Google API data is subject to the Google API Services User Data Policy. During background playback, track titles, artists and playback information appear in notifications, on the lock screen and in widgets. External file providers you select may process information under their own policies.
Retention, deletion and access withdrawal
Device lists, records and settings may remain until you delete the entries, clear app data in Android settings or uninstall the app. Clearing app data does not delete original audio. Disconnecting Drive stops playback and the app’s connection for that account, but lists and bookmarks may remain. Revoke Google access separately in your Google Account’s connected-app settings. Refusing or revoking access prevents Drive use; device files can still be played.
Support and your rights
Your sender address, message and attachments are used to answer your inquiry and deleted within 90 days after the inquiry is resolved. Do not send passwords or unnecessary personal files. You or your legal representative can use the contact email above to request access, correction, deletion, restriction of processing or withdrawal of consent for information held by the operator. Identity or authority is checked only as needed. Information stored only on your device can be deleted through the app or Android settings. Use Google Account and privacy controls for information held by Google.
Safeguards, children and changes
Lists, records and settings stored by the app are managed in app-private storage. Communication with Google is encrypted, and app data is configured to be excluded from backup. This app is intended for teenagers aged 13 and older and adults. It does not request age, date of birth or Play age signals. In Korea, consent-based processing of personal information of children under 14 requires consent from and verification of a legal representative. Children and their legal representatives can also use the contact above. Changes in processing and their effective date will be announced in the app and on the public policy page.
