...obviously. Even the most hardened irreversible encryption communication will have a source and destination. I'm sure nobody here needs to be told that you need two people to communicate (?).
Of course there is some form of internal "address" to route the information, but the separate chat instance does not advertise it, and being a 1:1 chat that information is not on any server or "cloud". Neither side specifically shows the others ID, reason being you cannot screenshot the conversation to show the participants. That is all I was saying, simple as that.
IE: Normal chat left, "private" chat right. One is saved unencrypted on the device, clearly lists both users, and can be saved or screenshotted. The other will delete itself after 60 seconds of inactivity, shows no easily identifiable personal information, has no valuable data to screenshot, and is a 1:1 conversation not hosted by any servers.
But again, I have been here long enough to know how people will always over complicate things for the sake of argument.
