## Permissions
This app requires only one Android permission:
- `android.permission.INTERNET`
The permission is declared in the app manifest (see `app/src/main/AndroidManifest.xml`) and is used only to fetch spot price data from the public API (spot-hinta.fi). No other runtime or sensitive permissions are requested.
## Verifying the installed app (AppVerifier)
1. Install the APK on the device.
2. Open the AppVerifier app on the device.
3. In AppVerifier:
- Select the installed app (Pörssisähkö) or point the tool to the APK file.
- View the app's signing certificate details: the tool should display certificate fingerprints (SHA1/SHA256).
4. Compare the displayed SHA1 and SHA256 fingerprints against the "Signing key fingerprints" listed in this README. If they match, the app is signed with the expected key.
