Privacy Policy

Last updated: April 6, 2026

1. Overview

ModiPDF ("we", "our", or "the Service") is a free, browser-based PDF editing tool available at modipdf.vercel.app. We are committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

2. No File Uploads — Local Processing Only

ModiPDF processes all PDF files entirely within your web browser using client-side JavaScript and WebAssembly technology (PDF-lib). Your files are never uploaded to any server. All editing, merging, splitting, compressing, and converting operations happen locally on your device.

This means we have no access to the content of your documents at any time. Once you close or refresh the browser tab, all file data is permanently removed from memory.

3. Information We Collect

While we do not collect your files, we may collect:

  • Usage analytics: Anonymous usage data such as page views, feature usage, and general interaction patterns to improve the Service. This data does not include any personally identifiable information.
  • Device information: Basic technical information such as browser type, operating system, and screen resolution to ensure compatibility and optimize the user experience.
  • Cookies: We use essential cookies to ensure the website functions properly. Third-party advertising partners (such as Google AdSense) may also use cookies to serve relevant ads. See Section 5 for details.

4. How We Use Your Information

The limited information we collect is used to:

  • Maintain and improve the functionality of ModiPDF
  • Analyze usage trends to prioritize new features
  • Ensure the Service is compatible with popular browsers
  • Display relevant advertising through Google AdSense

5. Third-Party Advertising (Google AdSense)

ModiPDF uses Google AdSense to display advertisements. Google AdSense may use cookies and similar technologies to serve ads based on your prior visits to this website or other websites. Google uses advertising cookies to enable it and its partners to serve ads based on your visit to our site and/or other sites on the internet.

You may opt out of personalized advertising by visiting Google Ads Settings. For more information about how Google uses data, please visit Google's Privacy & Terms.

6. Data Retention

Since your files are processed locally in your browser, we do not store any document data. Files exist only in your browser's memory during your session and are automatically discarded when you close the tab or navigate away from the page.

Anonymous analytics data may be retained for up to 26 months to help us understand long-term usage trends.

7. Data Security

Because ModiPDF operates entirely in your browser, your documents benefit from the security of your own device and browser environment. No file data travels over the network, which eliminates the risk of interception or server-side data breaches related to your documents.

8. Children's Privacy

ModiPDF is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe that a child has provided us with personal information, please contact us and we will take steps to delete such information.

9. Your Rights

You have the right to:

  • Opt out of personalized advertising via Google Ads Settings
  • Disable cookies through your browser settings at any time
  • Request information about any data we may have collected
  • Request deletion of any analytics data associated with your usage

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will post the updated version on this page with a revised "Last updated" date.
