Privacy Policy

Last updated: June 29, 2026. Learn how we protect your privacy when using our online slicer.

At STL to G-Code Converter, we prioritize the confidentiality and safety of your intellectual property and personal data. This Privacy Policy details our commitment to security and transparency.

1. Zero Server Uploads (Client-Side Slicing)

The core feature of this converter is 100% browser-based. When you upload or drag-and-drop a 3D model (in STL format), the file is read directly by your browser using local HTML5 and WebAssembly scripts. The files are never sent to, stored on, or processed by our servers. Slicing computations and G-code compiles occur strictly in your local device memory.

2. Information We Do Not Collect

Since we do not run backend processing servers for 3D slicing, we do not collect, capture, or store:

  • Your uploaded 3D design files (.stl, .obj, etc.).
  • Your customized slicing settings and output files (.gcode).
  • Names, files, or structure metadata of your 3D assets.

3. Web Analytics

To understand user volume and optimize website responsiveness, we utilize Google Analytics. This service uses cookies to collect standard, anonymized website usage metrics (such as page views, visitor regions, browser types, and session duration). No personally identifiable information or 3D design metrics are linked or sent to Google Analytics.

4. Local Storage Usage

Our application may store your slicing preferences (such as preferred layer height, print temperature, etc.) in your browser's local storage (`localStorage`). This is done strictly as a convenience so your custom settings persist the next time you visit. This data never leaves your browser.

5. Third-Party Links

Our website does not show external commercial advertisements, but may contain links to open-source libraries or documentation. We are not responsible for the privacy practices of external websites. We encourage you to read their policies.

6. Children's Privacy

Our service is fully safe for individuals of all ages as it does not collect personal identifiers or monitor private communications. Slicing tools can be freely used by students and hobbyists of all ages.
