VCZefb is an Android app for people who play online mobile football games. Its Rank Mode works as a local firewall: while your match is on, it pauses internet traffic from the other apps on your phone so they don't compete with the game. It runs entirely on your phone through Android's VpnService: no VPN server, no traffic relay, no IP change, and it never touches the game itself.
