Data & Account Deletion Instructions
Step-by-step guidance on how to delete all personal, sensor, and cultivation data for HydroGrow.
1. Offline-First Zero Server Storage Notice
HydroGrow operates on an Offline-First architecture. The Application has no centralized user accounts, no login servers, and no remote databases holding your personal information.
Because all your data exists solely on your local device (in the app's sandboxed SQLite database) and optionally in your own personal Google Drive, you have direct, instantaneous control over deleting 100% of your data at any time without waiting for developer approval.
2. Option 1: Complete In-App Factory Reset
To permanently and irrevocably erase all data from your device:
- Open the HydroGrow app on your Android device.
- Tap the Settings tab (gear icon in the bottom navigation bar).
- Scroll down to the Danger Zone section.
- Tap Factory Reset.
- Confirm the permanent reset.
What is deleted: All plant cycles, reservoir logs (pH, EC, water levels), notes, photos, custom nutrient recipes, calibration lab data, and application preferences are immediately and permanently removed from device storage.
3. Option 2: Delete Google Drive Cloud Backups
If you used the optional Google Drive backup feature, you can delete your backup archives at any time:
- Open Google Drive on your mobile device or at drive.google.com.
- Locate the
HydroGrow Backupsfolder. - Select and delete all
.hydrobackup files or delete the entire folder. - Empty your Google Drive Trash to permanently purge the files.
- In the HydroGrow app, open the Backup Center and tap Disconnect Google Drive to remove OAuth access tokens.
