App: Aquarium Chemistry Pro

Developer: Corithm Flow Matrix

Note: Aquarium Chemistry Pro does not require an account. All data (tank profiles, chemistry logs, maintenance tasks, and tank photos) is stored locally on your device. Uninstalling the app deletes all local data automatically.

Simply uninstalling Aquarium Chemistry Pro from your device permanently deletes all locally stored data, including:

All aquarium tank profiles
Water chemistry readings and history
Maintenance task schedules and completion records
Tank photo journal images
Cycling tracker readings and progress
Calculator history and saved results
App preferences and settings
Premium purchase status (note: Pro can be restored via Google Play)

Option 2: Clear App Data (keep the app installed)

To delete all local data while keeping the app installed:

Go to your device Settings
Navigate to Apps > Aquarium Chemistry Pro
Tap Storage & cache
Tap Clear Storage
