Lakrion

Lakrion is an encrypted messenger built for people and institutions where encryption alone is not enough.

Every messenger encrypts your messages. Lakrion goes further - working to protect your communication patterns, your identity, and your device.

Three layers of protection:

ENCRYPTION
Signal Protocol with PQXDH post-quantum key exchange (ML-KEM-768 hybrid) and the Double Ratchet algorithm. Post-quantum key exchange protects messages, voice calls, video calls, and push-to-talk. Forward secrecy helps keep past messages protected even if a key is later compromised.

METADATA PROTECTION
Sealed sender hides who sends each message. Cover traffic generates artificial communication to help mask real patterns. Connection randomization makes network fingerprinting harder. Tor support with kill-switch. No phone number required - your identity is generated on your device. Messages are deleted from the server after delivery, and within 24 hours regardless.

ATTACK SURFACE REDUCTION
Dormant Architecture (LDA) keeps high-risk subsystems like audio codecs, media decoders, and call handlers unloaded from memory until both parties consent. Code that isn't loaded into memory can't be exploited while it's dormant, which reduces the attack surface exposed at any given moment. When the call ends, these subsystems unload again.

Lakrion does not show ads, track you, or collect metadata about who you talk to or when.
