Mchat

Say 'hello' to privacy

Millions of people use Mchat every day for free and instant communication anywhere in the world. Send and receive high-fidelity messages, participate in HD voice/video calls, and explore a growing set of new features that help you stay connected. Mchat's advanced privacy-preserving technology is always enabled, so you can focus on sharing the moments that matter with the people who matter to you.

• Say anything – State-of-the-art end-to-end encryption (powered by the open source Mchat Protocol™) keeps your conversations secure. Privacy isn't an optional mode — it's just the way that Mchat works. Every message, every call, every time.

• Go fast – Messages are delivered quickly and reliably, even on slow networks. Mchat is optimized to operate in the most constrained environment possible.

• Be yourself – You can use your existing phone number and address book to securely communicate with your friends.

• Speak up – Whether they live across town or across the ocean, Signal's enhanced audio and video quality will make your friends and family feel closer.

• Whisper in the shadows – Switch to the dark theme if you refuse to see the light.

• Sound familiar – Choose custom alerts for each contact, or disable noises completely. Simon & Garfunkel wrote a hit song about it in 1964, and you can experience the sound of silence whenever you want by choosing "None" as your notification ringtone.

• Picture this - Use the built-in image editing features to sketch, crop, and flip your outgoing photos. There's even a text tool so that you can add more words to the 1,000 that your picture is already worth.
