Zero trace
ECDH key exchange with AES-256-GCM. Every conversation generates fresh keys. Runs entirely in your browser via Web Crypto API.
Close the tab and everything is destroyed. Keys, messages, identity — all gone. Nothing saved anywhere.
No phone number. No email. No registration. No identity. You're nobody — by design.
Works in any browser. Phone, laptop, tablet. Nothing to install. Send a link, start chatting.
Send text messages and voice notes up to 30 seconds. Everything encrypted end-to-end. Nothing stored. No photos, videos, or file sharing — by design.
Set a timer when you create a conversation. When time's up, the room is destroyed on both sides — even if nobody closes the tab.
Every line of code is on GitHub. The crypto runs in your browser. Verify it yourself.
Messages pass through a relay that holds only encrypted blobs in memory — nothing is written to disk. No accounts, no logs, nothing to hand over — even with a court order. Hosted in Helsinki, EU (GDPR).

Arnon runs entirely in your browser — no install, no sign-up, no trace.
Arnon is a free, self-hosted side project. There is no company, no investors, no monetization plan — just a single relay server and a browser app designed to disappear.
For stronger anonymity, use Tor Browser. Voice notes may not work in Tor Browser.
