Privacy Policy

Your Files Never Leave Your Browser

Your files never leave your browser. All 3D file conversions are performed entirely on your device using JavaScript and WebAssembly. No file content, file name, or file path is ever sent to our servers — because there is no server processing your files.

What We Collect

We collect a minimal set of anonymous, aggregated signals to understand how the tool is being used and to fix errors:

• Conversion format pair (e.g. STL → OBJ) — to know which conversions are most used
• File size bucket (small / medium / large — not exact bytes) — to detect performance issues
• Browser family (Chrome / Firefox / Safari / Edge) — to prioritize compatibility fixes
• Error codes (if a conversion fails) — to fix bugs

That's it.

What We Never Collect

We will never collect:

• File names
• File paths
• File contents
• Exact file size in bytes
• Any personal identifying information
