This add-on reads the Rust+ sign-in token and SteamID from Facepunch's companion page (companion-rust.facepunch.com) and sends them to rustconnect.net, together with a single-use linking code, to link your Rust+ account to your Rustconnect account. A single-use linking code is stored locally and deleted as soon as it is used. Nothing else is collected: no browsing history, no analytics, no tracking. Nothing is sold or shared with third parties.
