What is the source for "keeping messages" on a central server? I thought the whole point was end to end encryption and messages were stored locally on devices, no? I thought I read that CIA have a back door for it anyways, but I'm not sure any digital communications is 100% secure if they really want your data. Would love some discussion on this. That being said, Session looks cool. Telegram is probably my next move after Signal though.
Signal relies on centralized servers that are maintained by Signal Messenger. In addition to routing Signal's messages, the servers also facilitate the discovery of contacts who are also registered Signal users and the automatic exchange of users' public keys. By default, Signal's voice and video calls are peer-to-peer.[17] If the caller is not in the receiver's address book, the call is routed through a server in order to hide the users' IP addresses.[17]
But even without your messages being sent to a central server, the fact that Signal requires a phone number and then scans your phone book is enough reason not to use it.
For Metadata, its can be more valuable for a company to build a relationship map with all your contacts - learning the frequency of activity between two or more parties and find degrees of separation - than to read your messages at times.
