คำอธิบาย WiFi Analyzer

Users' privacy and security is a huge concern these days and WiFi Analyzer is designed to use as few permissions as possible. It asks for just enough to perform the analysis. Plus, it is all open source so nothing is hidden! Most notably, this application does not require access to internet, so you can be sure it does not send any personal/device information to any other source and it does not receive any information from other sources.
