Users interested in a secure messaging app with no user identifiers
About SimpleX
The first messenger without user IDs.
Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy.
Many users asked: if SimpleX has no user identifiers, how can it know where to deliver messages?
To deliver mesages, instead of user IDs used by all other platforms, SimpleX uses temporary anonymous pairwise identifiers of message queues, separate for each of your connections — there are no long term identifiers.
You define which server(s) to use to receive the messages, your contacts — the servers you use to send the messages to them. Every conversation is likely to use two different servers.
This design prevents leaking any users' metadata on the application level. To further improve privacy and protect your IP address you can connect to messaging servers via Tor.
Only client devices store user profiles, contacts and groups; the messages are sent with 2-layer e2e encryption.

"SimpleX review" Posted 2023-12-14
Pros: Security. Anonymous presence. Encryption. Availability for Windows 64, Android, iOS, and even the terminal.
Cons: Not too easy the first time. It may be a little hard to start with it when one is used to playing with another messaging app.
Overall: Good. Useful. Reliable. I'm actually very impressed; I've always looked for an messaging app that would not require phone number or something similar... It seems that I have found it.
