Offering a secure and feature-rich communication platform, Signal caters to individuals and groups seeking a privacy-focused alternative to mainstream messaging apps.

You can download and try one of those application as a alternative application for Signal: Skype, Zoom, Telegram.

Introduction: Built on a Foundation of Privacy

The Signal app started in 2010 as two different applications, RedPhone and TextSecure, which were made for Android devices. In the year 2015, these apps merged into one and got the name "Sigma." During that same period, Sigma was introduced to iOS users. Then in 2017, it became possible to use Sigma on desktop computers as well. Signal began its creation in 2010 aiming to build a messaging service that was secure for usage. Now, it has users in the millions globally who value privacy and prioritize security in their messaging. Sigma is now functional on different platforms such as Windows, macOS, Linux, iOS, and Android.

Why Choose Signal?

In a world where online privacy is a growing concern, Signal stands out for several reasons:

End-to-End Encryption by Default: Unlike many messaging apps where encryption is optional, Signal uses a robust protocol that encrypts all messages, calls, and video calls by default. This ensures only the sender and recipient can access the content of your conversations.

Focus on Open Source: Signal's source code is freely available for anyone to inspect, ensuring transparency and fostering trust in its security practices.

Disappearing Messages (Optional): Add an extra layer of privacy with disappearing messages that vanish from the chat history after a set time you choose.

Group Chats and Video Calls: Create group chats for secure communication with multiple contacts and enjoy encrypted video calls for face-to-face interactions.

No Ads or Data Tracking: Signal doesn't track your data or bombard you with advertisements, ensuring a clean and private communication experience.

Features Explained

End-to-End Encryption by Default: This is Signal's core strength. When you send a message, call, or video call on Signal, it gets encrypted with a unique code. Only the recipient's device possesses the key to decrypt the content, making it unreadable by anyone else, including Signal itself. This offers a significant layer of security compared to traditional messaging apps where messages might be stored on servers in unencrypted form.

Focus on Open Source: Signal's source code is publicly available, allowing independent security researchers and developers to scrutinize its functionality and identify potential vulnerabilities. This transparency fosters trust in the app's security practices.

Disappearing Messages (Optional): For conversations requiring an extra layer of privacy, Signal allows users to enable disappearing messages. These messages self-destruct from the chat history after a predetermined timeframe chosen by the sender, adding an element of impermanence to your communication.
