Privacy Policy

Key Point: 3DCompress processes all files entirely in your web browser. Your files never leave your device, are never uploaded to our servers, and are never stored anywhere. We have zero access to your documents.

Last updated: December 2024

1. Information We Collect

Files and Documents: We do NOT collect, store, or have access to any files you process using 3DCompress. All file processing happens entirely in your web browser using client-side JavaScript and WebAssembly technology. Your files never leave your device.

Website Analytics: We may collect anonymous usage statistics such as page views, browser type, and general location (country/region) to improve our service. This data is aggregated and cannot be used to identify individual users.

2. How We Process Your Files

When you use any tool on 3DCompress:

• Files are processed entirely in your web browser using JavaScript and WebAssembly
• Files are temporarily stored in your browser's memory (RAM) during processing
• Files are automatically cleared from memory when you close the browser tab
• No files are uploaded to our servers or any third-party servers
• No files are stored on any server or database
• We have no technical capability to access your files

3. Cookies and Local Storage

We may use cookies or browser local storage to save your preferences (such as theme choice or language settings). These are stored locally on your device and do not contain any personal information or file data.

4. Third-Party Services

CDN Services: We use Content Delivery Networks (CDNs) to load JavaScript libraries (such as PDF-Lib and PDF.js). These are industry-standard, open-source libraries that also process data client-side and do not transmit your files.

Analytics: We may use privacy-focused analytics services to understand how visitors use our site. These services collect only anonymized, aggregated data and do not track individual users or access your files.

5. Data Security

Since all processing happens in your browser and we never receive your files, your data security depends on:

• Your device's security (keep your OS and browser updated)
• Your browser's security (we recommend using latest versions of Chrome, Firefox, Safari, or Edge)
• Your network security (use HTTPS, avoid public WiFi for sensitive documents)

Our website is served over HTTPS, ensuring that your connection to 3DCompress is encrypted and secure.

6. Children's Privacy

3DCompress does not knowingly collect any personal information from children under 13. Our service does not require registration or personal information from any user, regardless of age.

7. GDPR Compliance

For users in the European Union, we comply with GDPR requirements:

• We do not process or store personal data or files
• We do not track individual users
• We do not share data with third parties (except anonymized analytics)
• You can use our service without providing any personal information

8. Changes to Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
