Secure P2P Connect · WAN Edition

Encrypted messaging over the internet, built on the open Nostr network. No accounts, no passwords, no central server holding your data — just a keypair you control and messages only you and the recipient can read.

How it works

STEP 01

Generate your identity

A cryptographic keypair is created right in your browser — that's your whole identity. No sign-up form, no password, no server that knows who you are.

STEP 02

Connect to the network

Your browser talks directly to public Nostr relays — lightweight, decentralized servers run by many independent operators, not by any single company.

STEP 03

Messages are encrypted first

Every message is sealed with real end-to-end encryption before it ever leaves your device — even the relay carrying it can't read what's inside.

STEP 04

Only the recipient can read it

Only the person you're messaging can decrypt it — from anywhere in the world with an internet connection, no local network required.

What you get

No Accounts

Nothing to sign up for. Your identity is a key you generate, not a registration.

Real Encryption

NIP-17 + NIP-44, via an audited library — not custom-built cryptography.

Works Anywhere

Any device with internet — not tied to a local network or a specific place.

Persistent Identity

The same key works across sessions — not regenerated every time like a session ID.

Local-Only Storage

Contacts and keys live in your browser. The app's server never sees them.

English & Japanese

Full bilingual interface, switchable anytime, remembered across sessions.

Security, stated plainly

  • Message content is unreadable to relay operators, or anyone intercepting network traffic — only sender and recipient hold the keys.
  • Sender identity is hidden from the network itself — each message is signed by a random, one-time key, not your real one.
  • No forward secrecy — this is a shared-key-style guarantee, not a per-session one. Stated honestly, not glossed over.
  • Lost key = lost identity. There is no password reset. Back up your key the moment it's generated.
