Privacy policy

Last updated 12 November 2026

nuts is made by Francium Tech. This policy covers the nuts apps for iPhone, Mac and Linux, and the nutsd, nuts-coord and nuts Home server software.

THE SHORT VERSION

Francium Tech doesn't collect any of your data. nuts has no accounts, analytics, advertising or tracking, and Francium Tech runs no servers your devices connect to. Your traffic goes from your device to a home server you run, coordinated by a coordinator you run. Francium Tech never sees it.

WHAT STAYS ON YOUR DEVICE

The app keeps these in its own storage on your device:

the pairing link from your server: your coordinator's address and its join key
the device's WireGuard private key, created on the device
the services and sites you chose, and your settings

The private key never leaves the device.

WHAT THE APP SENDS, AND WHERE

The app only talks to the coordinator in your pairing link, which you or the person who gave you the link runs. When you connect, it sends:

the device's WireGuard public key
the name of its platform (for example ios, macos or linux), used as the device name

The coordinator replies with your device's tunnel address and the list of home servers. Your public IP address is visible to the coordinator, as it is to any server you connect to.

YOUR TRAFFIC

While nuts is connected, traffic to the services and sites you chose goes through an encrypted WireGuard tunnel to your home server and out from there. On iPhone and Mac, lookups for those services' domain names go to your home server too. Everything else goes straight out over your normal connection.

If you turn on Route everything, all traffic goes to your home server, and its DNS lookups go through the tunnel to Cloudflare's public resolver (1.1.1.1), or to Tailscale's resolver on iPhone when your home server is on a tailnet.

The home server and coordinator software doesn't log the sites you visit or the names you look up. nutsd's own log on your home server records devices by name as they're added or removed.

WHAT YOUR COORDINATOR KEEPS

If you run nuts-coord, it saves this about each device and server that joins, on your own machine:

its name, whether it's a device or a server, and its WireGuard public key
its tunnel address
for servers, the public IP address and port devices reach it on
when it was last seen

Its log records when something joins and when a server's address changes. You control this data and can delete it at any time. Francium Tech has no access to it.

CAMERA

On iPhone, nuts asks for the camera only to scan the pairing code from your server. The code is read on the device. No images are saved or sent anywhere.

NO SELLING OR SHARING

Francium Tech doesn't sell, use or disclose any user data to third parties for any purpose. It doesn't receive any user data to begin with.
