Features Explained

End-to-End Encryption by Default: This robust security feature is the cornerstone of Signal. Unlike traditional messaging where messages are transmitted in plain text, Signal encrypts them with unique codes. Only the sender and recipient possess the keys to decrypt the content, ensuring maximum privacy for your communication.

Focus on User Privacy: Signal takes a strong stance on user privacy. It doesn't collect or store any user data, including your contacts, message history, or location information. This stands in stark contrast to many for-profit messaging apps that gather and monetize user data. By prioritizing privacy, Signal empowers users to control their communication.
