PROTOCOL

sender identity is untraceable

messages route through an anonymous relay. the server only sees the relay IP, never yours. even if the server is seized, your identity is not there.

server cannot read your message

encryption runs on your device before transmission. your private key never leaves your device — the server holds ciphertext only.

timing is randomised

a random 2–47 second delay is injected so timing correlation attacks cannot identify the sender.

destroyed after reading

5 seconds after the recipient opens the message it is permanently purged from the server. no backup. no log.

protocol · ecdh p-256 · aes-gcm 256-bit · hkdf-sha256
padding · 256-byte blocks — payload size does not leak
relay · all identifying headers stripped before forwarding
storage · private key is device-only, never transmitted
