InternetGuard is an application that allows you to block access to the internet on your mobile device. By doing so, it can help you reduce your data usage, save your battery, and increase your privacy. It also gives you control over which apps can access the internet and allows you to easily block or allow connectivity for specific apps. Additionally, it can block background app activity and alert you when new apps try to access the internet. It also has the ability to block adult websites.
The app is simple to use and does not require root access on your device. It does not call home, track your data, or collect analytics. It is actively developed and supported, and is compatible with Android 5.1 and later. It supports both IPv4 and IPv6 TCP/UDP and can be used with tethering and multiple device users. You can also choose to allow or block internet access for specific apps when your screen is on or when you are roaming. You can even block system applications if desired.
InternetGuard automatically launches on device startup and identifies all the apps currently installed on your device. It also notifies you when newly installed apps try to access the internet. You can set allow or block permissions for each app individually and disable background activity for selected apps. The app also provides full data usage visibility and has a material design theme with light and dark options. You can log all outgoing traffic, search and filter access attempts, and export PCAP files for traffic analysis. You can also allow or block individual addresses for each app and receive notifications for new apps accessing the internet.
InternetGuard is unique in that it uses your device's VPN package to create a firewall. This means that all data traffic is attributed to InternetGuard, making it appear as though it is using a lot of data. However, the app now has its own data usage feature that allows you to view the data usage for each app. This can be accessed from the home screen. It is important to note that the app is based on VPN interface and does not steal or send any of your data. The source code for the app is also available on GitHub for transparency.
In conclusion, InternetGuard is a comprehensive no-root firewall that offers a wide range of features to help you control your mobile apps and protect your data usage, battery life, and privacy. It is a reliable and secure option for those looking to block internet access on their devices.
