Privacy Policy

Last Updated: January 17, 2026

At DocuStitch, we believe your documents are your business. Our architecture is designed so that your sensitive data never leaves your computer.

1. Technical "Zero-Knowledge" Architecture

Unlike traditional online PDF tools, DocuStitch does not use a server-side processing model. We utilize WebAssembly (WASM) and client-side JavaScript to perform all document merging, splitting, and editing directly in your browser's RAM.

  • No Uploads: Your files are never transmitted to our servers.
  • No Storage: We do not own or operate databases that store your document content.
  • Local Memory: Data is cleared as soon as you close the browser tab.

2. Google Analytics (GA4)

We use Google Analytics to understand how visitors engage with our website. This help us improve the user experience and ensure our tool performs efficiently across different devices.

  • Data Collection: Google Analytics collects information such as your IP address, browser type, and pages visited. This data is used to analyze traffic patterns and site performance.
  • Anonymization: We have configured our analytics to respect user privacy and focus on aggregate trends rather than individual tracking.
  • Opt-Out: You can prevent your data from being used by Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

  • Consent Cookie: Used to remember your choice in the cookie consent banner.

5. CCPA & GDPR Compliance

CCPA: California residents have the right to opt-out of the "sharing" of personal information for targeted advertising. You can exercise this by selecting "Reject Non-Essential" in our cookie banner.
