This page is static files. Your message is encrypted in this tab and published straight to relays. Nothing we run ever holds a plaintext copy, because there is nothing to hold it.

Your message becomes an unsigned kind 14 rumor, sealed to the recipient as a kind 13, then wrapped in a kind 1059 under a key that exists only for that one event. Only the recipient can unwrap it.

A message signed with a one-time key carries a NIP-13 proof of work: your browser repeats a hash until the wrapper’s id begins with enough zero bits. That costs a visitor a few seconds, once. It costs a flood the same for every message, which is what lets an inbox relay refuse the cheap ones. A message signed with your own key skips it.

The recipient you chose, and nobody else. Every name offered is listed in this domain’s NIP-05 file. If you are signed in, you get a copy too, so the conversation appears in your own client.

An encrypted blob, the recipient it is addressed to, and your IP address, the same as any other connection you make. They cannot see who sent it, what it says, or when it was written.

Nothing this page can give us. No analytics, no logs, no third-party requests. The only network traffic this page makes is to nostr4.social and to the relays named on screen.

There is no forward secrecy in NIP-44: a key that leaks later can decrypt messages sent earlier. Relay operators can see metadata about the wrapper. If that matters for what you are about to say, say less here and more on a call.
