Signal Private Messenger

Open-source, end-to-end encrypted messaging app for text, voice, and video calls with minimal metadata retention.

Main Activities:

Signal is a privacy-first messaging app by a nonprofit foundation. It uses the Signal Protocol to provide end-to-end encryption for one-on-one and group chats, voice calls, and video calls. Messages, attachments, and user metadata are never logged on servers, and features like disappearing messages and registration lock PINs enhance security.
