At WattWise, we are committed to protecting your privacy. This Privacy Policy details our data practices regarding the WattWise mobile application (referred to as the "App").

1. No Data Collection

WattWise is a 100% offline application.

- We do NOT collect, gather, store, transmit, or share any personal information, usage stats, or telemetry data.

- The App does not contain any third-party SDKs, advertisements, or analytics packages (such as Firebase).

2. Local Processing Only

All appliance wattage estimations, kWh conversions, and cost rates calculations are performed locally on your device's memory. No data ever leaves your device.

3. Local Database Sandbox

Any logged appliances you choose to save inside the Energy Sandbox Logbook are stored strictly within the App's isolated local Room SQLite database on your device. You can clear this data at any time by:

- Purging files via the Settings menu inside the App.

- Clearing the App storage/cache in your Android system settings.

4. Device Permissions

WattWise does NOT require or request Internet access permissions. It operates fully offline-first.

5. Children's Privacy

Because we collect no personal data whatsoever, our App is safe for users of all ages, including children.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. However, our core philosophy of 100% offline usage and zero data collection will remain unchanged.
