Privacy Policy

Overview

STL Converter provides browser-based tools for converting images and 3D model files into STL files. This Privacy Policy explains what information is processed when you use this website and how that information is handled.

Files You Select

The core conversion tools are designed to run in your browser. When you choose an image, GLB, GLTF, OBJ, or FBX file, the file is read by your browser so the converter can generate a preview and STL output. In the current version, selected files are not intentionally uploaded to our server for conversion.

Browser object URLs and generated STL download links are temporary local browser resources. They are cleared when you reset the tool, leave the page, refresh the page, or close the browser tab.

Information We May Receive Automatically

Like most websites, hosting providers, security systems, and network infrastructure may process basic technical information such as IP address, browser type, device information, requested URL, referring page, and timestamp. This information is used for operating the website, security, abuse prevention, debugging, and reliability.

Cookies and Analytics

The current application code does not set non-essential cookies and does not include third-party analytics, advertising pixels, account tracking, or payment tracking. If analytics, advertising, accounts, payments, or other third-party services are added later, this policy should be updated before those services are enabled.

How Information Is Used

• To provide the browser-based STL conversion tools.
• To display previews and generate downloadable STL files.
• To maintain site security, availability, and performance.
• To troubleshoot errors and prevent misuse of the service.

Sharing and Selling

We do not sell selected files or generated STL files. We do not use selected files for advertising targeting. Technical logs may be processed by hosting and infrastructure providers that help operate the website.

Retention

Files selected for conversion are processed locally in your browser and are not intentionally retained by this website. Hosting and infrastructure logs, if any, are retained according to the retention settings of the relevant provider and used for security, operations, and debugging.

Your Choices and Rights

You can avoid selecting a file, reset the converter, clear your browser data, or close the tab at any time. Depending on where you live, you may have rights to request access, correction, deletion, or information about personal data that may be processed in connection with this website.

Children

This website is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so the issue can be reviewed.
