Group Chats: Signal supports group chats with end-to-end encryption for all participants in the group.
-
Privacy Features: Signal includes several privacy features, such as disappearing messages, screen security (preventing screenshots), and the ability to set message timeouts.
-
No User Data Collection: Signal collects very little user data, typically only the phone number used for registration. This focus on minimizing data collection contributes to its reputation as a privacy-centric app.
-
Security Protocol: Signal Protocol, the underlying encryption technology, is widely regarded as one of the most secure messaging protocols available.
Overall, Signal is favored by privacy advocates, journalists, and individuals looking for secure alternatives to mainstream messaging apps.
