1. Overview
DOCX Hub ("we", "our", "the service") is a client-side web application that provides free document viewing, editing, conversion, and metadata extraction tools. This Privacy Policy explains how we handle information when you use our website at docxviewer.online.
We are committed to protecting your privacy. Because our tools operate entirely within your browser using standard Web APIs, we have no technical capability to access your documents even if we wanted to.
2. Information We Do Not Collect
We do not collect, receive, process, or store:
- The contents of any document you open or upload
- Your name, email address, or any identifying information
- Your IP address or device fingerprint beyond standard web-server access logs
- Any files whatsoever because there is no file upload endpoint on our service
3. How Your Files Are Processed
When you select a DOCX, PDF, or other file using our tool, the browser's native
File API reads the file directly into volatile memory (a JavaScript
ArrayBuffer). The file is then processed by open-source libraries
running inside your browser tab:
- docx-preview: renders DOCX content as HTML
- Mammoth.js: converts DOCX structure to clean HTML
- Browser Print Engine: converts rendered content to PDF locally
At no point does any portion of your file data travel over the network. The data is automatically released from memory when you close or refresh the tab.
4. Local Storage & Browser Storage
We use browser localStorage exclusively for lightweight UI preferences such as theme settings (dark/light mode) or last-used tool. We do not store any document content, file names, or sensitive data in localStorage or any other persistent browser storage.
You can clear all locally stored preferences at any time by clearing your browser's site data for this domain (Settings → Privacy → Clear browsing data in most browsers).
5. Cookies
Our core service does not set any tracking or functional cookies. Please see our Cookie Policy for full details.
6. Analytics & Third-Party Services
We may use a minimal, privacy-respecting analytics service (such as Plausible Analytics or Cloudflare Web Analytics) to understand aggregate usage patterns, such as which tools are most popular. These services do not use cookies, do not collect personal data, and do not build user profiles. No individual user is identifiable from the data we receive.
We do not use Google Analytics, Facebook Pixel, or any cross-site advertising trackers.
7. Data Sharing & Sale
We do not sell, rent, share, or disclose any user information to third parties. Because we collect no personal data, there is nothing to share.
8. Security
Our website is served over HTTPS at all times, encrypting data in transit between your browser and our static-file CDN. Since files are processed locally and never transmitted, there is no server-side storage that could be breached.
9. Children's Privacy
Our service is not directed to children under 13. We do not knowingly collect any information from children. If you believe a child has inadvertently provided personal information through our service, please contact us and we will take appropriate action.
10. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. The "Last updated" date at the top of this page will be revised accordingly. Continued use of the service after a policy update constitutes acceptance of the new terms.
