PRIVACY
Solid Siege uses no server of its own and collects no user data. There are no accounts, no ads and no analytics.
Multiplayer is completely local. The device hosting a game runs a small web server on your own network, so that phones and tablets can join from a web browser by scanning the code on the host's screen. Nothing it serves or receives leaves your network.
Apple devices will ask for permission to find devices on your local network. That is how the host, the other Apple devices and the phones in the room find each other.
