My vague memory is that Signal doesn't keep that information, so it couldn't be subpeona'd, indeed they've been asked for it before and declined to share.

BUT IT'S MOOT IF YOUR MESSAGES ARE VIEWED by sender or receiver ON ANDROID, WINDOWS OR IOS. Those operating systems can just view everything you type regardless.

How does signal match your contacts based on their phone number then?

by having you trust intel instead of themselves: https://signal.org/blog/private-contact-discovery/

Oh but that's still better than I expected.

Hence "vague memory". I don't know.
