Encryption: Briar vs SimpleX
Briar uses e2ee with p2p — no servers involved. SimpleX uses e2ee with no user identifiers at all. The strength of encryption determines whether your messages can be intercepted and read by third parties, including the platform operator itself. For maximum protection, look for apps that encrypt everything by default without requiring manual activation. WeTalkin provides E2EE on all communications with zero-knowledge architecture.
