Zero-knowledge architecture.
By design, not by policy.

Your server never sees plaintext content. Messages, files, and call data are encrypted end-to-end using industry-proven cryptographic primitives.

  • X3DH + Double Ratchet — Forward secrecy and break-in recovery for every message
  • AES-256-GCM — Military-grade encryption at rest and in transit
  • Server-side zero knowledge — Messages are opaque blobs the server cannot decrypt
  • No metadata harvesting — No analytics, no tracking, no behavioral profiling
  • Configurable data retention — Set auto-delete policies aligned with your compliance needs
