Data privacy

Your measurements stay on your computer

Everything you drop in here is opened and calculated inside your own browser. Nothing is uploaded, nothing is stored on our server, nothing in the cloud, and nobody else can see or access it.

• Opened on your computer

  Your folders and project files are opened by your own browser, and every calculation runs on your own computer. The files are never sent anywhere.

• Nothing you load leaves

  Our server only supplies the app, the reference panels and the demo set. There is no upload, and the browser is told to refuse connections to any other site, so your measurements have nowhere to go.

• Your reports, on your disk

  PDF reports and spreadsheet exports are built in your browser and saved straight to your computer, where you choose.

• Gone when you close the tab

  Your measurements live only in the open tab. Close it and they are gone: nobody else can access your data.

• Two small things are remembered

  A cookie with your language choice, and, for as long as the tab is open, that you entered the password. Neither contains any measurement data.

The site is hosted on Vercel. Like any website, the host records which pages are requested and from which IP address. These logs contain no measurement data.
