What the app does
Signal Heatmap estimates local Wi-Fi, Bluetooth, and mobile signal activity so users can compare rooms and everyday locations. The app is designed for environment planning and does not provide medical advice.
Permissions
Depending on platform support, the app may request access for location, nearby Wi-Fi details, Bluetooth scanning, network state, and phone state. These permissions help produce signal summaries and scan history.
Scan data
Scan history is used to show saved readings, room summaries, and trend comparisons inside the app. Review the final production build and store disclosures before publishing to confirm whether any data leaves the device through analytics, crash reporting, ads, or other services.
Advertising
The app uses Google AdMob ads. Google and its partners may collect or process data for ad delivery, measurement, fraud prevention, and related advertising purposes according to Google's policies.
