Privacy Policy

Overview

PDFNinja is committed to protecting your privacy. This policy explains how we handle your data when you use our website and PDF tools. The short version: your files stay on your device, and we collect minimal analytics data to improve the service.

File Processing

All PDF processing on PDFNinja happens entirely within your web browser. When you use any of our tools — merge, split, compress, convert, edit, or any other operation — your files are processed using client-side JavaScript and WebAssembly technologies. This means:

• Your files are never uploaded to our servers or any third-party servers.
• We never see, access, read, or store your documents.
• Processing happens at the speed of your device, with no network transfer involved.
• Once you close the browser tab, all file data is cleared from memory.

Analytics

We use Vercel Analytics and Google Tag Manager to collect anonymous usage data that helps us understand how people use PDFNinja and improve the service. This data includes:

• Page views and navigation patterns
• Browser type and device information
• General geographic region (country level)
• Referring website

This analytics data is aggregated and anonymized. It does not include any personally identifiable information or any content from your PDF files.

Cookies

PDFNinja uses minimal cookies required for analytics and basic site functionality. We do not use cookies for advertising, tracking across websites, or building user profiles. You can disable cookies in your browser settings without affecting the core PDF tool functionality.

Third-Party Services

We use the following third-party services:

• Vercel — hosting and analytics
• Google Tag Manager — analytics tag management

These services have their own privacy policies. Importantly, none of these services ever receive or process your PDF files.

Data Retention

Since we do not collect or store your files, there is no file data to retain. Anonymous analytics data is retained according to the retention policies of our analytics providers (Vercel Analytics and Google Tag Manager).

Your Rights

Since PDFNinja does not collect personal data beyond anonymous analytics, there is minimal personal information associated with your use of the service. If you have questions or concerns about your privacy, please contact us.
