Sav PDF Viewer Pro is a simple and safe PDF viewer for Android devices. Developed by Saverio Morelli, this app allows you to view all your PDF files in a straightforward way while keeping your device secure as it does not require any permissions to run.

This PDF viewer automatically saves the last position for each file, and you can create bookmarks and manage them as well. Additionally, you can open PDFs that are protected by passwords. The app also comes with a night light feature to protect your eyes while reading in the dark. Sav PDF Viewer Pro is an open-source app and available on GitHub. However, it does not allow you to select or copy text, nor can you open links within PDF files.
