With my WifiMask apps it's the case as long as the on/off switch is turned on, the VPN will either be connected or try to connect, as long as there is no connection the kill switch will do it's work, prevent data leaking and the app will show what's going on. Only manually turning off the switch will disable the VPN and any data leaking protections. I can still do some improvements here and there to show more information on what's going on, so this is useful feedback to me, thanks.
