Signing in proves it's you. X tells us your account, and we read your own public profile (name, bio, the links in it) once. No posting, no DMs, and we don't keep X's access token.

Your recent posts are read in this tab through FxTwitter, an independent, unofficial service that reads public X posts. If it's unavailable, your bio alone is used.

What's kept: nothing, on our side. Your room lives in its link, which carries the interests you chose, the name on the plaque and, signed in, your handle, your profile picture's address and your products' sites (signed, so nobody can fake a room as you). Anyone you share the link with can read those. A guess, not a fact: change anything before you build. Not affiliated with X.
