About this app
GrapheneOS PDF Viewer is a simple, no-frills app for reading PDF files. It's built on pdf.js, a well-established PDF rendering engine, but runs it inside a locked-down sandbox so the PDF itself can't reach outside its own little box.
The app doesn't ask for any permissions, and PDFs are streamed in through a secure content link rather than given direct access to your files or the internet, so opening an untrusted PDF stays safe.
