  • NoRoot Firewall helps users who want to stop apps from sending data without permission. It focuses on app level control, so you decide which connections are allowed. For devices without root access, the NoRoot Firewall APK provides a straightforward way to manage traffic. However, LTE users may see issues because IPv6 is not supported yet. This approach can reduce unwanted data exposure while keeping everyday apps online. NoRoot Firewall Features Real-time connection control You receive a prompt whenever an app tries to access the internet. Choose Allow or Deny to control that request. This lets you stop unwanted connections in real time and keep visibility over app activity. Filter by IP, host, or domain Allow or block connections to specific IP addresses for an app. Set rules using host names to manage where an app can connect. Use domain based filters to keep traffic within approved sites. Straightforward interface NoRoot Firewall presents clear requests and saved rules in a simple layout, so you can review changes quickly. Additionally, navigation is direct, helping you focus on decisions instead of settings. If troubleshooting, confirm you are using the NoRoot Firewall latest version to avoid outdated behaviors. Minimal permissions The app itself requests minimal permissions. It does not access your location or phone number. This reduces exposure while you manage online connections for your installed apps. Start managing app connections To control internet access without root, download NoRoot Firewall and respond to prompts as apps request connections. Adjust rules to match your preferences, and monitor behavior on LTE if needed.

  • Look no further for your Android firewall. Mobiwol NoRoot Firewall can be used to save battery, reduce data usage so you stay within your data plan, and secure your privacy by limiting the network access permissions required by apps. With Mobiwol No Root Firewall you can - * Take Control Of Your Mobile Apps * Easily Allow/Block App Connectivity * Block background app activity * Be Alerted When New Apps Access the Internet Secure your phone or tablet, with reliable Android firewall protection - No ROOT access required! Regain control of your mobile device and what is being accessed and shared with the world. Features List Android firewall protection with **NO** ROOT REQUIRED!! Automatic launch on device start up Automatically identifies applications currently installed on your mobile device Identifies and Notifies when newly installed apps access the Web Set Allow/Block, on a per-application basis Disable background activity for selected apps Get full data usage visibility Install Mobiwol No Root Firewall for Simplified Android Security IMPORTANT: In the last update, a NEW NOTIFICATION ICON was added for STABILITY. We are working on finding a way to retain the stability without the icon, but please be aware that THIS IS NOT AN ISSUE. ***FAQS*** Why does Mobiwol No Root Firewall show as if using a VPN connection? This is superficial. We've used technology available to us from within the VPN packaging module offered by Android to be able to gain visibility to your applications' network activities and apply firewall rules without having to ask for root permissions like other Android Firewall apps. However, no actual VPN connection is being made, no data is being sent externally by our application, and we do not tamper with the security of your personal data, so you can continue using your apps with peace of mind, and confidence that you will not end up with a higher than usual data bill at the end of the month. ---------------------- Why Can't I accept the VPN Prompt? You will need to select the checkbox first and then the button becomes enabled. If you are having problems selecting the checkbox, it is likely that you have another app that creates an overlay on the active screen that is preventing you from selecting the checkbox. These two threads explain the problem further and give some examples of apps that do this- https://forums.openvpn.net/topic13455.html https://code.google.com/p/ics-openvpn/issues/detail?id=185 For more FAQs go to http://www.mobiwol.com/faqs.html ---------------------- Why does Mobiwol top the data usage chart? It’s an illusion. Mobiwol uses your device’s VPN package to create a firewall. As every data packet sent or received by your apps passes through the VPN, all the incoming and outgoing data traffic gets attributed to Mobiwol. The good part, however, is that Mobiwol now comes with its own Data Usage feature which allows you to check data usage for each app. To view the usage, choose Data Usage from the home screen.
