01 /
Zero persistence
RAM only. No files, no user-data logs, no cache. Explicitly zeroized on session close.
02 /
Zero knowledge
Keys derived client-side via X-Wing KEM (ML-KEM-768 + X25519). The server forwards opaque ciphertext it cannot decrypt.
03 /
Synchronous only
Both parties online simultaneously. No store-and-forward. Receiver offline — transfer doesn't start.
