WifiMask uses OpenVPN for the macOS app and IKEv2/IPSec for iOS. Examples of OpenVPN config files can be found at https://www.wifimask.com/contact#androidwindows which allows you to use the WifiMask service on every OpenVPN capable device. Meanwhile an Android and Windows app are in development, so stay tuned. ;-)
