Signal (encryption app)

Signal is a secure messaging app that uses strong encryption to protect your conversations. This means that only you and the person you're chatting with can read the messages, keeping them private from others, including the app itself. Signal offers features like text messaging, voice and video calls, and group chats, all secured through end-to-end encryption. It prioritizes user privacy, not collecting personal data or displaying ads, making it a popular choice for individuals concerned about their online security and privacy.
