No account to delete
Reaction Trainer has no server account or developer-hosted training database. Your training records are stored on your Android device. You can remove them with the controls below; a remote account-deletion request is not required.
Delete one training session
- Open Results in Reaction Trainer.
- Select the session you want to remove and use its delete action.
- Read the confirmation and confirm only if you want to delete it.
This removes the session and its individual attempts. Earned challenge completions and streaks remain.
Reset all training progress
- Open the app’s Settings.
- Choose Reset progress.
- Review and confirm the reset.
This removes all training and challenge history. Your preferences remain. The app cannot undo this operation.
Remove preferences and all local app records
In Android, open Settings → Apps → Reaction Trainer → Storage (wording varies by device), then choose the option to clear storage or clear app data. Clearing only the cache does not remove all app data. Uninstalling the app also removes its local storage.
These actions remove local preferences as well as local training records.
Check your Android backups
Android backup or device transfer may include app data when enabled. Older copies can remain with your device or account provider and may restore after reinstalling. Manage or delete those backups through that provider’s settings. STASH STUDIO does not control those copies.
Delete information you emailed us
If you previously contacted the studio and want to request deletion of that correspondence, email hello@stashstudio.site. Identify the earlier conversation without sending unnecessary sensitive information. The company will assess the request under applicable law, including any records it must retain.
