What makes SimpleX private
SimpleX Network
Simplex Chat provides the best privacy by combining the advantages of P2P and federated networks.
Unlike P2P networks
All messages are sent via the servers, both providing better metadata privacy and reliable asynchronous message delivery, while avoiding many problems of P2P networks. {{ overlay(simplex_network_overlay.sections[0]) }}
Unlike federated networks
SimpleX relay servers do NOT store user profiles, contacts and delivered messages, do NOT connect to each other, and there is NO servers directory.
SimpleX network
servers provide unidirectional queues to connect the users, but they have no visibility of the network connection graph — only the users do.
