NoRoot Firewall : Clever way to reduce mobile data

Most of the apps on your Android device probably require a data connection, and you may not even know when they are sending or receiving data. That's why your mobile data plan expires suddenly at an unexpected time. NoRoot Firewall puts you in control of Internet access for apps, as well as how they can access it.

As the name suggests, the app doesn't require you to root your Android. Instead, it creates a VPN and diverts all the traffic on your phone through it. This way, you can choose which traffic you want to allow and which you want to stop. When any app tries to access the Internet, you'll get an alert where you can allow or deny it and save the setting for the future. This level of control can also let you see when a certain app is accessing data for ads and block it. A VPN (Virtual Private Network) connection is the extension of a private network that includes links across shared or public networks, such as the Internet.

NoRoot Firewall also gives you the option to set up filters, both globally as well as for individual apps. Much like a VPN on your PC, these filters let you allow or deny connections to certain IP addresses.

My favorite part of the app is in its ability to specify if an app can access the Internet only over Wi-Fi, only over 3G/Data, neither or both. It gives you the control to tell your Dropbox or Play Store to only download when you're on Wi-Fi, or set some other app to be active only on 3G.

There's some bad news for 4G users though as NoRoot Firewall does not work well with 4G at the moment. And I'd like to issue a word of caution: while I'm using the app, those who are a bit careful about their privacy may not want an app that gets control over all the data transfers on their device.

Here are some reviews about NoRoot Firewall :

"Best app I've downloaded Firstly, thank you so much for this app! Its a cleaver and well-executed way to get around the rooted device method. Works exactly as advertised, and is well layed-out. Great policy and logging, but the only thing I would ask for is a "reset policies" button to clear the config."

"very useful works well. got it to work without being a geek and I like having more control over which apps communicate behind my back! (which recently they all seem to do without informing me to what ends) would be great if android would still tell me which of the allowed traffic consumed how much volume.. but that's really an extra. thanks for this app!"

"Feel like I live in a free country again In a world where every ounce of privacy is being taken and all our rights stripped the amazing team of grey shirts come to the rescue! Ecstatic would be an understatement so much anxiety gone ty my friends God bless you"
