As mentioned signal doesn't hide contact discovery. But it does a pretty good job of hiding who you are chatting to from everyone but OWS.
OWS received a Grand jury subpoena and was only able to produce "the only information we can produce in response to a request like this is the date and time a user registered with Signal and the last date of a user's connectivity to the Signal service.".
Certainly a NSL might compel OWS to add additional logging (and not talk about it). With that they could tell who messaged who, when the message was sent, and how big the message was.

- haffenloher 10y ago> Certainly a NSL might compel OWS to add additional logging NSLs cannot be used for that. They're a legal tool that can be used to extract certain types of information (such as subscriber information and maybe a little bit of transactional information) that a service provider already has stored on their servers [0]. However, they cannot be used to force a service provider to write and deploy code.

Anything that does TLS to connect to a single server can do that. Heck, if you do email to a single email server using secure IMAP and secure SMTP then PGP no longer leaks metadata.
