Privacy by Design

Your Files Never Leave Your Device

Unlike other PDF tools, PDFox processes everything locally in your browser. Open from Google Drive or your device. Process locally. Your files never touch our servers.

Our Privacy Principles

100% Client-Side Processing

All PDF editing, text extraction, OCR, and rendering happens directly in your browser. Zero server involvement. The browser itself acts as the sole processing and storage environment for your document — this is architecturally enforced by our patent-pending DNPR engine, not just a policy promise.

Your Files, Your Cloud

Open PDFs from Google Drive or your device. Everything processes in your browser — files never transfer to our servers. Your cloud, your control.

No Data Retention

Close the tab and your work is gone from memory. We have nothing to retain, nothing to breach, nothing to hand over. No document data, page content, font binary, or user edit is transmitted to any remote server at any point during the document lifecycle.

How We're Different

PDFox runs on your machine, in your browser. Here's what that means.

Other PDF Tools

  • Upload your files to remote servers
  • Store and process documents in the cloud
  • Retain files for days, weeks, or indefinitely
  • Vulnerable to data breaches and leaks
  • May use your data for AI training
