About this app

Mercury: Real Privacy is Peer-to-Peer.

Mercury is built on a simple, powerful principle: your conversations are yours alone. We've engineered a secure messenger that connects you directly to your contacts, no central servers in the middle.

Why Mercury is Different:

Mercury isn't just another encrypted messenger; it's a fundamental shift in how you communicate. By leveraging true peer-to-peer (P2P) technology, your messages, voice and video calls, images and files are transmitted directly from your device to your contact's device. We don't have servers to store your data, because your data never passes through us in the first place.

Your Privacy, Your Control:

* Anonymous Identity: Get started without a phone number or email. Your identity is a secure, anonymous key generated and stored exclusively on your device. You are in complete control.
* Self-Custody Keys: Your identity is protected by a 12-word recovery phrase. This and encrypted backups are the only ways to restore your account, ensuring only you have access.
* Encrypted & Local Backups: Create a fully encrypted, password-protected backup of your identity, contacts, and message history. Store it wherever you trust.

Core Features:

* True Peer-to-Peer Communication: All messages and calls are sent directly between devices for maximum privacy and minimal latency.
* End-to-End Encryption: Using a modern cryptographic stack (SSL, DTLS), every text, voice call, and video call is fully encrypted before it leaves your device.
* High-Quality Voice & Video Calls: Experience crisp, clear calls powered by the WebRTC framework.
* Secure Text Messaging: Chat with confidence, knowing your conversations are private and direct.
* No Registration: Forget handing over personal data. Your anonymous ID is all you need.
* Cross-Platform Core: Built on a high-performance C++ core, ensuring security and stability across platforms.

Your private communication where you're not the product, but the owner.
