XaephyrComms Secure P2P Connect

Privacy & Security Notice

Plain-language notice, not a formal legal document.

What this app is

XaephyrComms Secure P2P Connect gives you a persistent identity and encrypted messaging over the internet, via the public Nostr network. It's the internet-mode sibling to XaephyrComms Secure Off-Grid, built for when you have internet access and want messaging that isn't tied to a local network.

Read this before generating an identity

Your identity is a cryptographic key pair generated in your own browser. There is no account, no password reset, and no way to recover it if it's lost. Anyone who obtains your private key (nsec) can act as you. Back it up somewhere safe the moment it's generated — the app only shows it to you once.

What's stored, and where

Everything below is stored locally, in your own browser only:

What the app's own server sees

Nothing about your messages. The server hosting this page only ever serves the static app itself — once loaded, your browser talks directly to Nostr relays. There's no database, no account system, and no message content ever passes through infrastructure we operate.

A real third party in this picture: Nostr relays

Unlike the off-grid app, this one does depend on infrastructure we don't operate: public Nostr relays (by default, a small set of well-known ones). Worth being direct about what that means:

Encryption, stated plainly

No warranty

This is provided as-is, with no warranty of any kind, express or implied. In particular: there is no recovery mechanism for a lost key, no guaranteed message delivery, and no SLA on relay uptime, since relays are third-party infrastructure.

Acceptable use

This is provided in good faith for legitimate, lawful communication. Please don't use it to harass or threaten anyone, for anything illegal, or to abuse, overload, or attack the infrastructure it depends on — the relays, or the hosting this page runs on. Worth being direct about one thing: since messages are end-to-end encrypted, there's no way for us to monitor or moderate content even if we wanted to. That's the point of the encryption — but it also means acceptable use here relies on good faith, not enforcement from our side.
