No account to delete
Composition Trainer has no server account and does not send practice data to LOEBSTUDIO. The developer cannot delete or retrieve local practice data remotely. Use the controls below on each device where the data is stored.
Reset your practice progress
- Open Composition Trainer.
- Open Settings.
- Choose Reset progress and follow the confirmation shown in the app.
This deletes practice attempts, sessions, streak history, and explored-lesson markers. Saved items and preferences remain.
Remove saved items
Open Saved in the app and remove the items you no longer want. Reset progress does not remove saved items.
Delete all local app information
In Android, open Settings → Apps → Composition Trainer → Storage → Clear storage, or uninstall the app. Menu names vary by device. Clearing storage removes the app’s local progress, saved items, and preferences. This cannot be undone through the app.
Copies on another device
The app excludes its practice database and preferences from Android cloud backup. Android 12 and later may transfer the information to a new device through Android’s device-to-device transfer. Delete any copies already transferred on those devices as well.
Support correspondence
To ask about deleting information you voluntarily sent to support, email hi@loebstudio.website. Any applicable legal retention requirement may affect what can be deleted. Do not send passwords or unnecessary sensitive information.
