DataGuard user reviews :

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.

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.

I like this app it works well is easy on the eye and has plenty of options… but I do feel that a help section explaining them would be extremely useful (Not all users are tech savvy) All in all it works and does it’s job… no ads and it’s free so no complaints from me… You have nothing to lose by installing the app and you can feel safe in the knowledge that your phone is protected and safe. Thank you devs for all the work you have put into the app… well done

  • Hello! Thanks for your review and valuable suggestions, we’ll pass them along to our development team. Stay tuned!

DataGuard can’t install if NetGuard is installed! It’s one or the other, can’t install both! I understand that most people wouldn’t use both apps, but it not unusual to try to install both just to test them. Thete is no information why both can’t be installed. It just says can’t be installed. So I’m left guessing (I had to uninstall 9 of the most recent apps to discover the cause). I’m sure many would have hard reset their phones I’ve given 4 stars, but I’ve still not used the app.
