Privacy Policy

1. Everything happens locally
This tool is 100% client-side. We don't have a backend server for file processing, so your 3D models are never uploaded anywhere. The conversion from OBJ to STL happens directly in your browser's memory using JavaScript.
2. No tracking
There are no tracking scripts, analytics tools, or ads on this site. I don't know who is using the site or what models are being converted.
3. Cookies
We don't use any cookies. If we add custom settings in the future, they will be saved to your browser's localStorage, which never leaves your device.
Verify it yourself
You can check the network tab in your browser's dev tools—no requests are made when you convert a file. You can even disconnect from Wi-Fi right before clicking the file, and it will still work perfectly.
