Very Useful and user friendly No doubt this VPN based firewall is the best on its kind  very stable with all features any android user will need..Using android with Marcel's xprivacy and netguard combined is a much better android experience .I hope more users supports this dev therefore he """"""""maybe"""""""" drop the """"""""firebase"""""""" implementation which is ruining the concept of the app. Thank you""
