Signal Private Messenger is a secure communication app that prioritizes user privacy through end-to-end encryption. It allows users to send texts, voice messages, photos, videos, and files while avoiding traditional SMS and MMS fees by using the phone's data connection.

The app supports crystal-clear encrypted voice and video calls, including group calls for up to 50 participants. With group chats supporting up to 1,000 people, Signal provides robust admin permission settings to manage group members and control posting privileges.

Signal also offers Stories that disappear after 24 hours, allowing users to share images, texts, and videos with customizable privacy settings. As an independent, non-profit organization, Signal does not collect user data or display ads, ensuring complete privacy and security.

Signal Private Messenger stands out with its strong focus on privacy and security. The app uses the open-source Signal Protocol, which ensures that no one, not even Signal, can read your messages or listen to your calls. This commitment to privacy extends to its lack of backdoors and data collection practices.

One of Signal's key features is its ability to make encrypted voice and video calls, including group calls for up to 50 people. The app also supports large group chats with up to 1,000 participants, providing admin controls to manage who can post within these groups.

Additionally, Signal offers Stories that disappear after 24 hours, giving users a way to share temporary content with specific privacy settings. Being a non-profit supported by donations, Signal avoids advertisements and investor pressures, focusing solely on user privacy and experience.
