About

Session is an end-to-end encrypted messenger that minimizes sensitive metadata, designed and built for people who want absolute privacy and freedom from any form of surveillance. Session accounts are completely anonymous. No phone number or email required. Session doesn’t collect data, so there’s nothing to leak. Send messages through our onion routing network and leave no trace. Session’s code has nothing to hide. Anyone can view, audit, and contribute. With no central point of failure, it’s harder to shut Session down. Talk to your friends or talk to the world. You decide. Closed groups let you talk to up to 20 friends at once, with the same encrypted protection as one-on-one chats. Got a bigger crowd? Use an open group to connect with as many people as you want. Sometimes, a text just isn’t enough. Voice messages let you send something a little more personal, so nothing gets lost in translation.

About

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.

Pros & Cons from Real Users

Pros

  • I found session 2 years ago when it was just put out and was in love, no sign up or logs, top notch encryption and u can dump and create new accounts as quick and easy as pushing a button. Session is the future.
  • The range of features and the actual current demonstrated capabilities and omissions are grand. Open source is critically important and their protocol is based upon tried and true protocols from safe developers. It's a shame you can't trust their situation as an entity - as all of this can become irrelevant immediately in the blink of an eye under a number of plausible - likely, even - scenarios. This weakness must be addressed.
  • Free and open source. End-to-end encrypted messenger. Decentralized. Doesn't require phone number or email. No meta data tracking.
  • Decentralized. E2e encrypted. No email or number required. P2p v.soon. Faster than tor. Easy interface.

Cons

  • It was buggy, but they were working on it. I also noticed something, called sentinel? A file that someone was trying to send me, in the past I've ran into it and believe it's a form of spyware, probably just the person I was chatting with, but idk...
  • You won't find privacy from apps developed in Australia or by Australians. Period. This is very suspicious and what is secure today may be very quickly made insecure and revelatory retrospectively in one quick patch. Do not trust any company at the mercy of Australian lawmakers. Because even they have no say over the matter if push comes to shove.
  • Not really a con of the app but Session is not really popular.
  • Design is not so cool as compare to signal or others.

Pros & Cons from Real Users

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.
