Privacy-focused messaging platform with encryption

About Signal

Signal provides a messaging platform that prioritizes user privacy through end-to-end encryption. This means that messages and calls made through Signal are secure and can only be accessed by the intended recipients, ensuring that even Signal cannot read users' messages. The platform includes features like voice and video calls, group chats, and encrypted stickers, all available without long-distance charges. What sets Signal apart from its competitors is its nonprofit status, which allows it to operate independently without relying on advertising or user tracking for revenue. Instead, it is funded by grants and donations from users and supporters. The goal of Signal is to offer a secure and private communication service for individuals and groups who value their privacy.
