Features

Disable internet access when on mobile or/and Wi-Fi for specific apps. This can be useful to avoid watching videos accidentally by using mobile data.
Custom deny firewall rule
This can be used for example to define a custom firewall rule to block ads for Chrome-based apps on port 53 for all IP addresses:
com.android.chrome||53 for Chrome, com.sec.android.app.sbrowser||53 for Samsung Internet, etc.
Whitelist a domain for a specific app
For when you want to block a domain systemwide, but you still need this domain for a particular app that won't work without it.
Instead of whitelisting the app, you can just whitelist that domain for this app.
Example: Block the domain graph.facebook.com systemwide, but allows it for Facebook Messenger so that it can be used for login:
com.facebook.orca|graph.facebook.com
