Privacy

Your files

Files you open on this site are never uploaded. There is no server that receives them. Conversion happens in your browser, on your own machine, using code that was downloaded to your device along with the page.

This is not a policy promise that you have to take on trust. You can check it. Open your browser’s developer tools, go to the Network tab, and convert a file. You will see no request carrying your file.

When you close or reload the page, the file is gone from memory. We do not keep a copy, because we never had one.

What we store on your device

This site’s own code stores nothing. It does not use browser local storage or session storage. Your settings are not saved between visits, which is a deliberate trade: it means there is nothing about you sitting in your browser after you leave.

This site sets no cookies of its own. Two of the analytics services described below, Google Analytics and Microsoft Clarity, may set their own cookies to tell one visit from the next. The third, Cloudflare Web Analytics, sets none. There is no advertising, so there are no advertising cookies.

Analytics

This site uses Microsoft Clarity to understand how the pages are used: where people click, how far they scroll, and where they get stuck. Clarity records these interactions and can replay a visit as a reconstruction of the page, and it collects things like your browser, device, rough location and the pages you visited. It may set cookies to do so.

Clarity does not receive your files. A file you open is read into your browser’s memory and never becomes part of the page, so it is not in what Clarity records. Names of files and of the objects inside them are masked, so they do not appear in recordings either. Clarity masks what you type into form fields by default.

Microsoft processes this data under the Microsoft Privacy Statement. We use it only to improve the site and do not sell it or join it to anything else.

This site also uses Cloudflare Web Analytics to count page views and measure how fast pages load. It receives the address of the page you are on, the page that linked you to it, how long the page took to load, and your browser, device type and country. It does not use cookies or store anything on your device, and it does not receive your files or anything shown on the page. Cloudflare processes this data under the Cloudflare Privacy Policy.

This site also uses Google Analytics to count visits and understand where visitors come from and which pages they use. It receives the address and title of the page you are on, the page that linked you to it, some of your interactions such as scrolling and link clicks, and your browser, device and rough location. It sets cookies to recognise a returning browser. It does not receive your files. Google processes this data under the Google Privacy Policy; you can read how Google uses information from sites that use its services, or install the Google Analytics opt-out add-on.

Our hosting provider, Cloudflare, keeps standard server logs of requests for security and reliability. These contain things like the page requested, the time, and a truncated network address. They are held by Cloudflare under their own privacy terms and we do not join them to anything else.

Third parties

Microsoft Clarity

The analytics service described above. Its script is loaded from clarity.ms on every page, and it sends what it records back there.

Cloudflare Web Analytics

The page-view counter described above. Its script is loaded from static.cloudflareinsights.com on every page, and it reports to cloudflareinsights.com.

Google Analytics

The visit counter described above. Its script is loaded from googletagmanager.com on every page, and it reports to google-analytics.com.

Content delivery networks

Some formats need a large piece of compiled code to read. That code is downloaded from jsDelivr, a public open-source code network, and only when you open a file that needs it. jsDelivr sees the request for that code file, as any web server does. It does not receive your 3D file.

Advertising

There is no advertising on this site at the moment. No ad network loads on any page, and none can: the site’s security policy blocks them.

That may change, because running the site costs money. If it does, this page will be updated before the first ad appears, and it will say which provider is used and what it may store on your device. In regions where consent is required, you will be asked first.

Links to other services

Some pages list 3D printing, laser cutting or CNC services. These are ordinary links. We have no affiliate arrangement with any of those services and earn nothing if you use them.

Children

This site is a tool for working with 3D files and is not directed at children. We do not knowingly collect information from anyone.

Your rights

Because we do not collect personal information, there is generally nothing for us to show you, correct, or delete. If you have written to us by email, that email exists in our mailbox, and you can ask us to delete it.

Changes

If this policy changes in a way that affects you, the change will be described on this page. The current version applies from the date this page was last updated: 24 October 2026.
