#Signal #Lifehack. When you register as new user, Signal asks you to provide "a" phone number where it can send a confirmation code to finalise the setup.
Know that it asks for "a" phone number that can receive messages. It doesn't have to be YOUR phone number. This is not a new feature, it has always been like that. I registered my Signal account using the phone number of a prepaid SIM in a cheap burner phone. I have never used that number since.
The only thing Signal stores about you is
- When did you register your account (UNIX timestamp)
- When was the last time your account contacted a Signal server (UNIX Timestamp)
That's it. That's all Signal can produce about you when they are forced to by authorities. There is no history, no call log, no data beyond that.
Here you can see a subpoena asking for detailed information and the reply that Signal sent back: https://signal.org/bigbrother/cd-california-grand-jury/
@jwildeboer that is all that is stored on their disks sure, but it is naive to pretend like that's the only useful thing that could come from their servers
