Very good app, crucial to have an app of this type on all smartphones in my opinion. Allows you to lockdown apps using data & sending information from your phone to servers who knows where. In settings on Android under the "Apps" section if you choose a specific app you can turn off the apps ability to use background data. However, numerous apps seem to be able to override this but not with this!

Wonderful free firewall. Works very similar to Zonealarm for the desktop, which I have had running for over 2 decades. This is the one piece I have been missing for my android devices. If you can control what communicates to the rest of the world then the device will be a lot more secure. I have installed software on my PC before that shouldn't have required to communicate with the internet but was asking for permission. I would deny them and then uninstall the software.

i really love it. you should add a donate option in the menu list. i will donate, just don't like monthly subscription. no complaints, it would be nice if you could allow app access and block a range of ip addresses for individual apps. it can be grueling doing it 1 ip at a time.. then they cannot change the last ofset by 1 digit and get throw again.
