What is Signal?
Signal is a messaging and calling application focused on privacy and security. It is designed for individuals who want to communicate securely, offering an experience that prioritizes confidentiality. The application is built on end-to-end encryption, ensuring that conversations remain private. Users communicate by sending text messages, voice messages, photos, videos, GIFs, and files. They can also make voice and video calls to other people. Signal supports group chats for connecting with family, friends, and coworkers, and allows for the use of encrypted stickers, including custom-made packs.
