Encrypted Messaging

Encrypted Messaging brings together tools for people who want their everyday conversations to come with stronger privacy protections by default. Signal is the most straightforward starting point here: a free encrypted messenger for chats, voice and video calls, groups, media, and file transfers, run by an independent nonprofit with no advertising or tracking-based business model. Session and SimpleX Chat take a more identity-minimizing approach, avoiding phone numbers or persistent account identifiers and leaning on open-source designs, disappearing messages, private connections, and community features. Delta Chat offers a different route again, building encrypted messaging on email-style infrastructure rather than a single central chat network.

This subcategory also includes options for people and organizations thinking beyond a single app. Element and Matrix.org sit in the decentralized Matrix ecosystem, where encrypted chat, calls, federation between servers, bridges, integrations, SDKs, hosting options, and open specifications are part of the picture. Element is especially relevant for teams and institutions that want more control over their communications infrastructure, including cross-organization and higher-security deployment scenarios. Taken together, these listings are a useful map of encrypted messaging today: from simple private conversations, to decentralized networks, to self-hosted and protocol-level approaches for those who want to understand or control more of the stack.
