📝 About Signal
Signal is what messaging looks like when a protocol, not an ad business, decides the design. Every message, call, photo, and voice note is end-to-end encrypted by default — no incognito modes, no settings to forget. Sealed sender technology hides even the metadata of who talks to whom.
The Signal Protocol is so respected that WhatsApp, Google Messages, and others adopted it for their encryption. The difference is everything around it: Signal is run by a nonprofit foundation, stores almost nothing, tracks nothing, and costs nothing. WhatsApp using Signal’s protocol while harvesting business telemetry is the comparison that fills privacy talks.
Its limitation is network: Signal is only as private as your conversation partner’s choice of app. For the people you actually trust, it’s the messenger security professionals use to talk to each other.
