Very good app, crucial to have an app of this type on all smartphones in my opinion. Allows you to lockdown apps using data & sending information from your phone to servers who knows where. In settings on Android under the "Apps" section if you choose a specific app you can turn off the apps ability to use background data. However, numerous apps seem to be able to override this but not with this!

After MOTO update, DaGu App notifications broke. Attempted Network Access Notifications supposed to be different colors depending if app access was connected or blocked. After today's Moto upgrade all notifications are black. Please change the notifications put a "b"locked and "a"llowed b4 entries. Night mode notifications r grey from all Apps.

I cant make this up but after looking for 3 different apps, I ended up picking apps created by the same developer without knowing or meaning to, however there is ZERO communication or support as of yet. UPDATE: This app seems to be a clone of the app "NetGuard - no-root firewall"
