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.
Built from the ground up for absolute privacy and security, Y Communicator sets a new standard for secure communications.
Protected against future quantum computer attacks with ML-KEM (Kyber) key exchange and Dilithium signatures. Your messages stay secure for decades to come.
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.
Messages relay through a decentralized network of RAM-only nodes. No single point of failure, no centralized data storage, no permanent records.
Servers never see your messages, never know who you're talking to, and never store your data. Even if compromised, attackers get nothing useful.
Communicate via rotating cryptographic addresses that can't be linked to your identity. Change addresses hourly or per conversation for maximum privacy.
Messages are deleted from relay nodes immediately upon delivery. Undelivered messages expire automatically. No permanent server-side storage ever.
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.
Keys stored in secure hardware (Keychain/Keystore)
