There are apps and games which may continue to access the internet in the background services even when you exited
Therefore you should consider blocking apps from accessing the internet to reduce your data usage increase your privacy save your battery.


NetBlock gives you all of those features:
- Safe and easy to use
- No root required

Some notes:

- This app only sets up a local VPN interface to be able to block the network traffic of apps without root. So you can trust that it does not connect to a remote server to steal your private data.

- You cannot use another VPN at the same time.

- You may need to add NetBlock app to the whitelist of the battery optimization to keep it working.
