Private Messaging for the Quantum Age

We collect nothing. No email. No phone number. No name. No location. No personal data of any kind. Y Communicator delivers uncompromising privacy with post-quantum encryption and complete anonymity. Just install and communicate — we'll never know who you are.

Why Y Communicator?

Built from the ground up for absolute privacy and security, Y Communicator sets a new standard for secure communications.

🔒

Post-Quantum Encryption

Protected against future quantum computer attacks with ML-KEM (Kyber) key exchange and Dilithium signatures. Your messages stay secure for decades to come.

👤

No Accounts Required

No phone numbers, no emails, no usernames. Generate your identity locally and communicate with complete anonymity. We can't identify you because we never ask.

🌐

Distributed Network

Messages relay through a decentralized network of RAM-only nodes. No single point of failure, no centralized data storage, no permanent records.

🚫

Zero Knowledge Design

Servers never see your messages, never know who you're talking to, and never store your data. Even if compromised, attackers get nothing useful.

🔄

Anonymous Addresses

Communicate via rotating cryptographic addresses that can't be linked to your identity. Change addresses hourly or per conversation for maximum privacy.

🕐

Auto-Delete Messages

Messages are deleted from relay nodes immediately upon delivery. Undelivered messages expire automatically. No permanent server-side storage ever.

Security Without Compromise

Y Communicator assumes the worst: that servers may be compromised, that traffic may be monitored, and that quantum computers may eventually break today's encryption. Our architecture is designed to remain secure even in these scenarios.

  • AES-256-GCM encryption for message content
  • ML-KEM (Kyber-class) post-quantum key exchange
  • Dilithium-class signatures for authentication
  • Private keys never leave your device
  • RAM-only relay nodes with no disk storage
  • Metadata minimization with rotating addresses
