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.

would have rated higher if not for the forced 'Rate Us' request every single time i use the app. other than that the app works well. blocks apps that you want blocked. helps save on data as you dont have every app on your phone pinging the network all the time

So my first impression is good, but even though the APP claims no data collected and no data shared with 3rd parties I can't help but worry that the VPN does not abide by these rules. I would like to configure my own VPN but i couldn't find an option to select my already installed VPN instead, only options for exact network addresses. Very useful, but the VPN that provides functionality to the APP needs more transparency..

Hello! Thank you for your feedback. Unfortunately, you can not use another VPN app together with Data Guard. For a real VPN try our Full Tor VPN. Data Guard blocks access to the internet only.
