Privacy Policy

At PDFMummy, your privacy and trust are our top priorities. We build our tools to be simple, safe, and transparent. This Privacy Policy explains how your files and information are handled when you use PDFMummy.

File Handling & Zero Uploads

PDFMummy uses client-side processing for supported tools. With these tools, your documents are processed directly inside your web browser instead of being uploaded to our servers.

  • Zero Server Uploads: Supported client-side tools do not require your documents to be sent to or stored on PDFMummy servers.
  • Local Processing: Supported conversions, merges, splits, and edits are performed directly within your web browser using client-side technology.
  • No File Retention: When a supported client-side tool processes your document locally, PDFMummy does not receive or store that document on its servers.

Test It Yourself

You don't have to simply take our word for it. You can test the client-side processing of a supported tool yourself:

  1. Open PDFMummy while connected to the internet.
  2. Open a supported PDF tool, such as Merge PDF or PDF to JPG.
  3. Turn off Wi-Fi and mobile data.
  4. Upload your file and perform the conversion.
  5. Download your converted file.

If the supported tool continues to process your file after your internet connection has been turned off, the processing is taking place directly in your browser rather than requiring an upload to our server.

Note: Offline processing applies to supported client-side tools. Some tools or features may require an internet connection to load or access certain resources. Please check the individual tool for its specific requirements.

Information We Collect

We believe in data minimization. PDFMummy does not collect, process, or store the content of documents processed locally by supported client-side tools.

We may collect limited technical and anonymous usage information for website analytics, performance monitoring, security, and improving our services, such as:

  • Browser type and general device information.
  • Approximate usage statistics and pages or tools visited.
  • Referring website or page, when available.
  • General technical information needed to maintain website performance and security.

Analytics and advertising services may process information according to their own privacy policies and settings.

Cookies & Third-Party Ads

PDFMummy is supported by advertising and may use third-party services such as Google AdSense to display advertisements.

  • We or our advertising partners may use cookies and similar technologies to measure advertising performance and, where permitted, provide relevant advertisements.
  • Advertising services do not receive access to the local files you select inside supported client-side PDF tools simply because you use those tools.
  • You can manage cookies, browser permissions, and personalized advertising preferences through your browser and the relevant advertising provider.

Your Privacy Rights

Depending on where you live, you may have privacy rights under applicable laws, including rights relating to access, correction, deletion, restriction, objection, or certain choices regarding personal information.

Because documents processed by supported client-side tools are not uploaded to our servers, we generally do not have access to the contents of those documents.

If you have questions about privacy, analytics, advertising cookies, or your rights, contact us at support@pdfmummy.com.

Data Security

Our approach to document privacy is straightforward: when a document can be processed locally in your browser, it does not need to be uploaded to our server.

This client-side approach reduces the need for server-side document storage and transmission for supported tools. However, no website or technology can guarantee absolute security, so we encourage users to keep their browser, operating system, and devices up to date.

Third-Party Links

PDFMummy may contain links to external websites and services. We are not responsible for the content, security, or privacy practices of external websites. We encourage you to review the privacy policies of those websites before sharing information with them.

Updates to This Policy

We may update this Privacy Policy from time to time to reflect changes in our services, technology, legal requirements, or privacy practices. Any updated version will be posted on this page with a revised Last Updated date.
