Privacy Policy
Last updated: February 2026
Summary
Polyvia3D processes your 3D files entirely in your browser. Your files are never uploaded to our servers. We do not collect, store, or transmit any of your 3D model data.
File Processing
All 3D format conversion is performed locally in your web browser using WebAssembly technology. When you select a file for conversion, the file is read directly by your browser and processed on your device. The converted output file is also generated locally and downloaded directly to your device. At no point are your files transmitted over the internet or stored on any external server.
Data We Collect
We may collect standard web analytics data to understand how our service is used and to improve the user experience. This may include:
- Pages visited and time spent on each page
- Browser type and version
- Device type (desktop, mobile, tablet)
- Referring website
- Approximate geographic location (country level)
We do not collect any information about the files you convert, including file names, file sizes, or file contents.
Cookies
We may use essential cookies to ensure the proper functioning of our website. We may also use analytics cookies to understand how visitors interact with our site. You can control cookie preferences through your browser settings.
Third-Party Services
We may use third-party analytics services (such as Google Analytics or Plausible Analytics) to collect and analyze usage data. These services have their own privacy policies governing how they handle data.
Data Security
Since your files are processed locally and never transmitted to our servers, the risk of data breach for your 3D model files is effectively zero. We use HTTPS encryption for all web traffic to protect any analytics data in transit.
Changes to This Policy
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
