Zero-Knowledge Architecture

Privacy Policy

Last updated: October 2026

1. Our Zero Server Storage Guarantee

At PDFPulse (accessible from https://pdf-pulse.devilabshq.com), privacy is our fundamental product principle. Unlike traditional online document converters that upload your PDFs and photos to cloud servers, PDFPulse processes your documents 100% locally inside your web browser.

When you merge, split, or convert documents on PDFPulse:

  • Your documents never leave your computer, tablet, or phone.
  • No document data or contents are ever transmitted to our servers or third parties.
  • All file manipulation happens strictly in temporary browser memory (RAM) using client-side WebAssembly and JavaScript.
  • Closing or refreshing your browser tab immediately erases all document references.

2. Information We Do NOT Collect

Because processing is client-side:

  • We do not collect or store your file names, document text, images, or metadata.
  • We do not require user accounts, emails, passwords, or personal details to use any tool.
  • We do not maintain user activity databases or document logs.

3. Web Analytics and Cookies

To monitor uptime, performance, and website health, we may use privacy-preserving web analytics (such as Cloudflare Web Analytics) that measure page load times and aggregate anonymous visits. These tools do not track personal identifying information (PII).

4. Third-Party Advertising & Partner Disclosures

To maintain our service completely free of charge, we may display third-party advertisements (such as Google AdSense). Third-party ad vendors, including Google, use cookies to serve ads based on a user's prior visits to this or other websites. You can opt out of personalized advertising by visiting aboutads.info or Google Ads Settings.
