From, the only info that's leaked is:

  • message date
  • sender/receiver addresses
  • message size

So not nothing, but probably not a serious risk for most people, unless you decide to use an identifiable address for sending/receiving. Idk how Signal protects metadata, but it requires a real phone number, so it's probably not as secure as people think.

Delta doesn't support perfect forward secrecy nor post quantum encryption. It's more secure than people think.
