Privacy policy
Last updated: 3 November 2026
Short version: no cookies, no accounts, no ads, and the generator runs entirely in your browser.
What we collect
We count visits with Ahrefs Web Analytics. It does not use cookies and does not follow you across other websites. It records anonymous, aggregated information such as which pages are visited, the website that linked to us, the country and the type of device.
What stays on your device
The generator, the 3D preview and the PDF are all made in your browser. Your measurements are not sent anywhere. Your choice of units and paper size is saved in your browser's local storage so the site remembers it next time. You can clear it at any time in your browser settings.
Hosting
The site is hosted by Vercel. Like any web host, Vercel processes technical data such as IP addresses to deliver pages and protect the service. Fonts are served from our own domain, so no font service sees your visit.
Changes
If this policy changes, the date at the top of the page changes with it.
