Introduction: From Thought Experiment to Global Movement

Signal was released for the first time in 2010 under two applications called RedPhone and TextSecure. This application was developed for Android. In 2015, they merged RedPhone and TextSecure into one application, “Sigma.” The same year, Sigma for iOS was released, and in 2017, it was released for desktop. Signal's journey began in 2010, driven by the desire to create a secure messaging platform. Today, it boasts millions of users worldwide who value privacy and prioritize secure communication. Now you can use Sigma on any device, like Windows, macOS, Linux, iOS, and Android.

Why Choose Signal?

In a world where data privacy is a growing concern, Signal stands out for its unwavering commitment to user security:

End-to-End Encryption by Default: Unlike many messaging apps, Signal uses end-to-end encryption by default on all communication channels, including messages, calls, and video calls. This encryption scrambles message content, ensuring only the sender and recipient can access it.

Disappearing Messages: Add an extra layer of privacy with disappearing messages that self-destruct after a set time chosen by the sender. This feature is ideal for sensitive information or casual conversations.

Focus on User Data Protection: Signal prioritizes user privacy. It doesn't store user data like message content, call logs, or contact lists on its servers. This minimizes the potential for data breaches and ensures your communication stays private.

Open-Source Development: Signal's code is open-source, meaning anyone can inspect and verify its security features. This transparency fosters trust and allows the security community to contribute to the app's ongoing development.

Free and Non-Profit: Download and use Signal for free. It operates as a non-profit organization, free from advertising or intrusive data collection practices.
