    Caveats of federation: Metadata leaking

    When using federation, Matrix’s room states (containing a lot of Metadata) get replicated and stored indefinitely on every homeserver any user connects with or connects to. While this is a feature for enabling distributed chat rooms, it comes at a serious privacy cost.

    To avoid this, you can either disable federation, or make sure that your users signed up with no linkable identifiers other than their user names.
