   Contact graph is who you are sending messages to. Signal servers can always see who receives a message and they can trivially see who sent a message if sealed senders is turned off (which, as is shown, can be done by the server). So Signal in fact has access to your contact graph.

   They also have access to a bunch of other metadata, like the Apple/Google push token that is known to be used to spy on people: https://www.reuters.com/technology/cybersecurity/governments-spying-apple-google-users-through-push-notifications-us-senator-2023-12-06/
