The Trusted network feature works like an exceptions list: when you add a network to it, you will no longer get connected to a VPN server when using that network. In other words, by adding a network to the Trusted Network list, you are saying that you trust this network, thus you do not need VPN protection while being on it. This can be convenient when traveling from a safe network environment, such as your home, to a riskier one, like a free-access Wi-Fi hotspot at a cafe. Without having to lift a finger, the NordVPN connection will automatically turn on or off based on what networks you add to the Trusted Network list.
Here you can find the instructions tailored to your device:

Users of Android, be aware: The 'Wi-Fi exceptions' feature will no longer be available on Android 10 OS or later versions due to its incompatibility with their latest security updates. It will still be available on devices running older Android OS versions.
