Milling know-how

What happens to my uploaded CAD file?

In short: your file is transferred encrypted via HTTPS, processed on servers in Germany exclusively to generate the G-code, and then deleted automatically — after 24 hours at the latest. It is not analysed, not shared and not used for any other purpose. No account is required, so the file is not tied to any profile.

CAD files are often more than geometry: designs for customers, prototypes, parts under NDA. That is why it pays to look closely at what an online service does with them — here is the complete process.

Upload a file and generate G-code →

The path of your file, step by step

  1. Upload: the file travels TLS-encrypted to the server — nobody can read it on the way.
  2. Processing: the server reads the geometry and computes the toolpaths from it.
  3. Download: you download the finished G-code and check it in the preview.
  4. Deletion: file and job data are deleted automatically, no later than 24 hours after the upload.

No analysis, no sharing

The file is processed purely by machine to generate the G-code — it is not analysed, not sold and not passed on to third parties. Server logs (IP address, timestamp) are kept for operations and debugging for a maximum of 30 days. The full retention periods and legal bases are in the privacy policy.

Where the processing takes place

Processing runs on Hetzner servers in Germany, so the GDPR applies directly. The CAD file itself is not transferred to third countries for G-code generation.

For particularly sensitive parts

If you mill parts under NDA, you can reduce the risk further: export only the single part you need from the assembly, choose a neutral file name and leave out drawing details that play no role in machining.

To be honest: if your contract forbids uploading anything at all, you need a locally installed solution such as EstlCAM or dxf2gcode — and pay for it with installation and training effort.
