Legal & Privacy Information

Terms of Service

Welcome to Vaultzen PDF. By using our service, you agree to these terms. Our editor is provided "as is" and is designed solely to facilitate the secure modification of your local documents. You are solely responsible for the documents you upload, edit, and export.

Zero Liability Policy

Because Vaultzen PDF operates 100% strictly within your own browser via client-side processing, we do not have access to, cannot see, and cannot monitor the contents of your documents.

Therefore, we assume zero liability for the content, accuracy, legality, or any consequences arising from the modifications you make to documents using our tool. You are entirely responsible for the final exported document.

Privacy & Cookies

We believe in absolute privacy. We do not use tracking cookies, analytics cookies, or advertising cookies. The only data we store locally on your device are basic functional preferences (like your recent scale settings or temporary session IDs for the mobile scanner).

How We Process Data

Your files never leave your device.

  • When you select a PDF, it is loaded directly into your browser's memory (RAM).
  • All text, signatures, and redactions are drawn mathematically within your browser using JavaScript.
  • When you click "Export", the final PDF is generated on your device and downloaded directly from your browser's memory.
  • No document data is ever sent to, processed by, or stored on our servers.
  • Exception: If you use the "Scan with Phone" feature, the photo is temporarily relayed through an end-to-end encrypted WebSocket connection solely for the purpose of bridging your phone to your computer. The photo is destroyed from the relay immediately upon transmission and is never written to disk.
