Multipart3D
Open tool

Privacy

Privacy here is not a setting. It is how the tool is built.

  • ✓Your files never leave your device. Loading, cutting and exporting all happen locally in your browser.
  • ✓Nothing is uploaded to or stored on a server.
  • ✓No account, no login, no sign-up.
  • ✓No analytics, no tracking, no cookies for advertising.

Because Multipart3D is a client-side web app, your STL and 3MF files stay in the browser tab you open. That is the product design, not a toggle buried in settings.
