Privacy Policy

This Privacy Policy explains how PDF Dark Mode handles information when you use pdfdarkmode.org. The short version: the PDF files you choose are processed locally in your browser and are not uploaded to our servers for reading or conversion.

Last updated: May 14, 2026

Local PDF Processing

PDF Dark Mode is designed to process your documents in your browser. When you open a PDF in the reader or use the download tool to create a dark mode PDF, the file stays on your device during that session.

We do not receive, store, review, or attach your PDF files to an account. Refreshing or closing the page clears the active PDF session from the browser interface.

Because processing happens in your browser, you should avoid emailing us sensitive PDF files unless you decide it is necessary for support and you are comfortable sharing them.

Information We May Collect

We may receive basic technical information that browsers normally send to websites, such as IP address, browser type, device type, referring page, pages visited, timestamps, and error information. This information helps keep the site secure and understand general usage.

If you contact us by email, we receive the email address and any information you choose to include in your message.

How We Use Information

  • To operate, maintain, and improve PDF Dark Mode.
  • To respond to support requests sent to support@pdfdarkmode.org.
  • To diagnose technical problems, prevent abuse, and protect the service.
  • To understand aggregate usage patterns, such as which pages are visited most often.

Cookies and Local Storage

PDF Dark Mode may use browser local storage to remember interface preferences, such as the selected language. These settings stay in your browser and help the site feel consistent when you return.

If analytics or security tools are added in the future, they may use cookies or similar technologies. We will use them for site operation, security, and aggregate measurement rather than to inspect your PDF files. You can usually clear local storage and cookies through your browser settings.

Third-Party Services

We may use hosting, security, analytics, or email providers to run the website and respond to users. These providers only process information needed for those services. They do not receive your PDF files from the reader or converter because PDF processing happens locally in your browser.

Data Retention

PDF files are not stored by PDF Dark Mode. Support emails may be retained as long as needed to answer your request, maintain records, or comply with legal obligations. Basic server or security logs may be retained for a limited period for reliability and abuse prevention.

No Sale of Personal Information

We do not sell your PDF files. We also do not sell personal information collected through support emails or routine website operation.

Security

We use reasonable technical and organizational measures to protect the website. No internet service can be guaranteed to be perfectly secure, so you should use care when deciding what information to send by email or through a browser.

Your Choices

You can choose not to contact us by email, clear browser storage, or stop using the site at any time. Depending on where you live, you may have rights to request access, correction, or deletion of personal information you have provided to us, such as support email records.

Children's Privacy

PDF Dark Mode is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us so we can take appropriate action.

Changes to This Policy

We may update this Privacy Policy when the site changes or when legal requirements evolve. The updated version will be posted on this page with a new last updated date.
