Signal doesn’t have access to your messages; your chat list; your groups; your contacts; your stickers; your profile name or avatar; or even the GIFs you search for. As a result, our response to the subpoena will look familiar. It’s the same set of “Account and Subscriber Information” that we provided in 2016: Unix timestamps for when each account was created and the date that each account last connected to the Signal service.
