About Signal
Signal is a free, open-source messaging app developed by the Signal Foundation, a US nonprofit. It provides end-to-end encrypted text messages, voice calls, video calls, and file sharing — with no ads, no data collection, and no back doors. As of early 2025, Signal has approximately 70 million monthly active users globally.
Unlike most messaging platforms, Signal cannot read your messages or metadata. The app is available for iOS, Android, Windows, macOS, and Linux. Signal does not have a web client by design — this is a deliberate security decision to prevent server-side compromise.
