Privacy Policy
WallCraft is a free browser game. We don’t ask you to create an account, and we don’t run our own database of players. This page explains the little data that is involved and how advertising on this site works.
Information you give us
The only thing we ask for is a display name so other players can see who they’re playing against. It is stored in your own browser (local storage) so you don’t have to type it again, and it is shared with the other people in any lobby you join. Please don’t use your full real name or other personal details as your display name.
Information stored on your device
- Local storage: your display name.
- Session storage: a random identifier for your browser tab and, if you host a lobby, a copy of that lobby’s state so a page refresh doesn’t end the game. Session storage is cleared when you close the tab.
You can delete this data at any time by clearing your browser’s site data for this website.
Online play (peer-to-peer)
Online games connect players’ browsers directly to each other using WebRTC. The lobby creator’s browser runs the match. To set up those connections:
- A matchmaking (“signaling”) service, PeerJS, briefly exchanges connection details between players’ browsers.
- Public STUN servers operated by Google help browsers find a route to each other.
- Because the connection is direct, other players in your lobby can see your IP address, as with most peer-to-peer games and video calls.
Game moves and lobby details are sent only between the players in that lobby. We don’t store game history on any server.
