Lumen

Lumen is a messaging application developed by Meta (formerly Facebook) that allows users to communicate via encrypted messages, voice calls, and video chats. It prioritizes user privacy and security through end-to-end encryption, meaning only you and the person you're communicating with can see or hear your conversations. Lumen is designed for private, secure, and instant communication, making it suitable for both personal and professional use. It functions across multiple devices, ensuring seamless messaging experience regardless of your platform choice.
