FAQ

Q: Is this app safe to use, and does it collect any of my personal data?

A: You can absolutely trust this app with your privacy because it is completely open-source, meaning its code is fully transparent and vetted by volunteers. Furthermore, the application operates entirely offline, requires zero internet access, has no ads, and does not harvest or track your data.

Q: Why does the app ask for my location permission if it is just scanning Wi-Fi?

A: This is a common point of confusion, but starting from Android 9 and newer, the Android operating system strictly requires Location Services to be enabled for any app to perform Wi-Fi scans. Rest assured, WiFi Analyzer only requests the absolute minimum permissions needed to run its diagnostics and does not track your actual physical location.

Q: How do I know which Wi-Fi channel is the best one for my router to use?

A: The app makes this incredibly easy by providing automated channel ratings. It analyzes all nearby wireless traffic, evaluates channel congestion, and clearly highlights the optimal channels so you can configure your router for peak performance.
