Privacy

Your PDF documents and reading activity stay on your device. MJ PDF has no ads or tracking.

If the app crashes, you can choose whether to send a technical diagnostic report to help identify and fix the problem. A crash report is never sent without your approval and does not include your PDF documents.

Storage or All files access is used only to discover, open, rename, delete, and manage PDF documents across device storage and removable storage.

Internet access is used to open PDFs from links and to send a crash report only when you explicitly approve it.
