Signal Private Messenger

Signal is a cross-platform centralized encrypted messaging service developed by the Signal Technology Foundation and Signal Messenger LLC. It uses the internet to send one-to-one and group messages, which can include files, voice notes, images, and videos. It can also be used to make one-to-one and group voice and video calls.

Originally launched in 2014 by Moxie Marlinspike as a merger of the TextSecure and RedPhone apps, the brand represents a commitment to privacy through open-source software. Unlike many competitors in the tech space, the product is not manufactured in a physical sense but is developed and maintained by a non-profit organization focused on cryptography and privacy rights.

The service is owned and operated by a non-profit foundation, ensuring that there are no corporate shareholders or surveillance-based business models. This structure allows the platform to remain independent of the typical commercial pressures found in the tech industry.
