Signal

Advanced encryption for every chat and every call.

Signal is an open-source, encrypted messaging service designed for instant messaging, voice calls, and video calls. It ensures that all communication is private and secure through end-to-end encryption, meaning only the sender and recipient can access the messages.

End-to-End Encryption: Signal uses the Signal Protocol to encrypt all messages, calls, and media, ensuring that no third party, including Signal itself, can access your conversations.

Cross-Platform Compatibility: Available on Android, iOS, and desktop platforms, Signal allows seamless communication across devices.

Group Chats and Calls: Supports group messaging and voice/video calls with up to 40 participants, all encrypted end-to-end.

File Sharing: Users can send text messages, voice notes, images, videos, and other files securely.

Disappearing Messages: Offers an option to set messages to automatically delete after a specified time, enhancing privacy.

Minimal Data Collection: Signal collects minimal metadata and does not store or sell user data, ensuring privacy.

Signal is developed by the Signal Technology Foundation, a nonprofit organization dedicated to promoting secure global communication through open-source privacy technology.
