NEXUS

Your data. Truly yours.

Settings, scenes and signed packages that live on devices you own. Sync between your phones. Named by hash. We cannot read it. Transit from your node is free.

What it is

A smart backup for your settings. That you own.

Change a color on your phone — saved. Walk to another room, grab a tablet — same color. Visit a friend, use their iPad — it syncs there too. And you own all of it.

Private copy

Your app keeps a private copy on the phone. Off internet? Still works.

Local first

Live sync

When online, phones, tablets and watches see the same state in seconds.

Peer sync

You own it

We cannot read it, sell it, or lock you out. Keys stay with you.

E2E
How it works

Private copy. Sync. Smart conflicts.

1

Your copy. Data lives on your phone first. You control it. Offline never breaks.

2

Sync. Online devices exchange signed changes. We verify authenticity, then get out of the way.

3

Conflicts. Two edits offline? Earliest signed change wins. No random last-write.

What makes it different

Offline. Instant. Encrypted. Portable.

Works offline

No internet? Adjust settings, create scenes, organize devices. Sync when you reconnect.

Always usable

Real-time sync

Phone change lands on tablet and watch in seconds. No polling screens.

Instant

End-to-end

Encrypted with keys only you hold. We do not have the ability to decrypt it.

ML-DSA-65

One-tap setup

New device? Open the app. Snap a QR. Done. Ownership is cryptographic.

No WiFi dance

Any maker

Buy from us, an independent maker, or a co-op. Signed open firmware works the same.

No lock-in

Instant transfer

Sold a device? Ownership moves in seconds. Old owner loses access the same instant.

Companies · Factory · gateway

Run a Nexus node on your own machines.

Hash-named firmware and packages stay on hardware you control. Bytes your node serves are Nexus transit — free. The over-the-internet path is Galaxy Direct.

Factory fleet

The Factory's k3s cluster on Raspberry Pi boots Helm charts with a Nexus node on every host. Normal k3s — install any other chart beside them.

Gateway + --nexus

Start the zero trust gateway with --nexus. Signed firmware and packages stay on your machine, authenticated with post quantum identities.

Not blockchain. Not an NFT. Just hardware.

A key on the device. One valid chain.

People hear “cryptographic” and assume a public ledger. It is not. The ownership chain — the signed history of everyone who has owned this device — lives on the device itself. No nodes. No consensus. No coin.

Ownership is a key burned in at the factory. Whoever holds the device holds the key. A MAC address identifies the chip; the key proves ownership. Backup to an encrypted cloud blob is on by default — we cannot read it. Prefer pure hardware-only? Turn it off.

Having a copy on your phone and a copy in the cloud does not create two chains. Same key. Same signed history. The crypto only ever recognizes one valid chain at a time. The device is the source of truth.
