Pry-Fi

Pry-Fi is an app developed by Chainfire, the creator of SuperSU. The objective of this app is to protect the information about your WiFi networks. The constant leaking of information is something that normally happens without you realizing. In fact, you need to deactivate the option 'Background Network Scanning' to prevent it, an option that many users don't even know exists.

The objective of Pry-Fi is to stop your information from leaking unnecessarily by completely deactivating your Internet connection. Once activated, it will stop your device from 'announcing' the WiFi networks it knows, without losing the possibility of connecting to known WiFi networks.

Pry-Fi is an app that's especially useful for users who connect to public WiFi networks. That said, your device needs to be rooted in order for the app to work correctly. If it's not, then you won't be able to use all the app's features.
