Vaultex · Encrypted messaging · Huntsville, AL

Private messaging that keeps working when the network doesn't.

Vaultex is end-to-end encrypted, zero-knowledge messaging. The server stores only encrypted data, you need no phone number, and messages can travel over the local network, Bluetooth and mesh relay when there is no internet.

What Vaultex does

01

Zero-knowledge by design

The server stores only encrypted data. It never holds plaintext messages or private keys, so there is nothing readable on it to leak or hand over.

  • End-to-end encryption
  • Sealed sender
  • No phone number or email
  • Keys stay on your devices

What you get

  • Messages only the people in the conversation can read
  • A relay server that cannot read your messages
  • An identity built on cryptographic keys, not a phone number
02

Works with no internet

When connectivity fails, Vaultex can deliver messages directly between nearby devices over the local network and Bluetooth, and relay them across other devices in range.

  • Local network
  • Bluetooth
  • Mesh relay

What you get

  • Messaging where there is no cellular or internet service
  • Delivery across several nearby devices, not just one hop
03

One core, five platforms

One cryptographic core is shared by the Windows, macOS, Linux, Android and iOS clients, so every client uses the same encryption code.

  • Windows
  • macOS
  • Linux
  • Android
  • iOS

What you get

  • Desktop installers and a mobile app
  • End-to-end encrypted voice and video calls
