Privacy

Last updated 17 September 2026

Your files are never uploaded

Every tool on this site runs inside your browser. When you drop an STL, an OBJ or a photo onto a page, that file is read by your own browser and the geometry is computed on your own machine. It is never sent to this site or to anyone else, because there is no server here doing that work. The site is a set of static pages, and once they have loaded they need no further connection.

No accounts, no cookies

There is nothing to sign up for, so no email address, name or payment detail is ever asked for or stored. The site sets no tracking cookies and no advertising identifiers.

Aggregate traffic measurement

To know whether anyone is using the tools, this site may use Cloudflare Web Analytics, which is cookieless and does not fingerprint visitors. It records page views, referrer, country and browser type in aggregate. It cannot identify you, and it has no access to your files.

Hosting

The pages are served by Cloudflare Pages, which (like every web host) processes your IP address in order to deliver the page and keep the service up. The 3D viewer loads the three.js library from the cdnjs content delivery network. Opening a less common format fetches one more reader from jsdelivr at that moment: a small script for FBX, glTF, PLY, 3MF or DAE, or a WebAssembly CAD kernel of about 3 MB for STEP and IGES. Those CDNs therefore see that a reader was requested, and your IP address, in the same way as any other file on a web page.

Your file still does not move

It is worth being exact about the paragraph above, because it is the one place this site talks to anything else. What travels is the parser coming to your browser, not your model going anywhere. Every one of those readers runs locally on your machine, on a file the page read from your own disk, and none of them uploads what they parse.

Changes

If this ever changes, for example if a paid feature is added that does need a server, this page will say so before it happens, and the browser-only tools listed here will stay browser-only.
