OpenBreath has no account and no server. Your measurements are held on your own phone, and a backup exists only in your own Google Drive if you chose to create one. That means you can delete everything yourself, immediately, without asking anyone.
In the app, open Account → Delete all data and confirm. This removes every measurement, name and tag from the device. Uninstalling the app also removes its storage.
The backup lives in a hidden folder that belongs to this app alone. Removing the app's access to your Google account deletes that folder with it:
| Data | Deleted by | Retention |
|---|---|---|
| Measurements, names, tags, settings, the last connected device | Account → Delete all data, or uninstalling | Immediate. Held only until you do this. |
| Google Drive backup file | Removing the app's access in your Google account | Held until overwritten by a later backup or removed by you. |
| Your email address and name, if you signed in | Signing out in the app, or Delete all data | Stored on the device only, never sent to us. |
| Anonymous analytics and diagnostics (Firebase Analytics) | Uninstalling the app stops collection. Google retains it under its own schedule. | Cannot be tied back to you by us: it contains no measurements, name or email. |
There is nothing held on our side to delete, because there is no server and no account. If you still want to make a request, or you cannot complete the steps above, write to info@apneastatic.com and we will respond with the steps for your situation.
