Status History
What is Signal?
Signal is an open-source messenger launched by the Signal Foundation in 2014. The app is renowned for its strong emphasis on privacy and security, making it a preferred choice for users worldwide who wish to keep their communication confidential. Signal uses the proven Signal Protocol for end-to-end encryption, ensuring messages and calls are protected from unauthorized access. The app is not only known for its encryption technology but also for containing no ads or tracking, setting it apart from many other messaging applications.
Unlike many commercial alternatives, Signal is a nonprofit organization funded by donations. This independence allows it to focus fully on the interests of users without compromise.
The Company Behind Signal
The Signal Foundation, founded by Moxie Marlinspike and Brian Acton in 2018, is the driving force behind Signal. Marlinspike, a renowned cryptographer, previously worked at Twitter and was instrumental in developing the Signal Protocol. Brian Acton, co-founder of WhatsApp, left the company after its sale to Facebook and invested $50 million in founding the Signal Foundation. The organization's headquarters is located in Mountain View, California.
The Signal Foundation is an independent, nonprofit organization, meaning it is not dependent on large technology companies and is not at risk of corporate takeovers. This ensures that user privacy is the top priority.

The installation process is simple, and the app requires no extensive training.
Notably, Signal requests no unnecessary permissions and respects user privacy. The app is minimally designed, which facilitates operation and minimizes distractions.
Privacy & Security
Signal is a pioneer in privacy matters. The app uses the robust Signal Protocol, also used by other known apps like WhatsApp and Skype, to ensure secure end-to-end encryption. This means that only the communication participants have access to the content.
The data is not stored on servers, and there are no cloud backups, further enhancing security. Signal is subject to U.S. laws, but without the obligation to store metadata, making it one of the safest communication platforms.
