pdfium-binaries vs PdfViewer

pdfium-binaries

📰 Binary distribution of PDFium (by bblanchon)

Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions. The PDF stream is fed into the sandboxed WebView without giving it access to content or files. CSP is used to enforce that the JavaScript and styling properties within the WebView are entirely static. (by GrapheneOS)

There are some pdf readers that protect you against those things.
On Android, for example, there is the GrapheneOS Pdf Viewer [1]. It's readme has a pretty good explanation of how it works.

Secure PDF Viewer. FOSS. The Simple Rick of PDF viewers. Reads PDFs and doesn't spy on you. At the time of this writing, printing PDFs with this app is a bit awkward. You have to use the "Share" button and then scroll down to the printer icon or "send to printer" icon to print the PDFs. MJ PDF Reader also belongs in this slot. FOSS. Printing PDFs is simpler and easier with this app.
