Messengers (for example Signal)

Messengers like Signal are secure communication apps that allow people to send text messages, voice notes, images, and videos over the internet. They use encryption, which scrambles messages so only the sender and recipient can read them, protecting privacy from outsiders. This makes conversations private and difficult to intercept or eavesdrop on. Many messengers also support features like group chats and voice or video calls, enabling seamless communication while prioritizing security and user privacy. They serve as modern, encrypted alternatives to traditional SMS, connecting people reliably and privately worldwide.
