Foldio is a PDF scanner and personal document library for Android - no subscription, no account, no ads. Scan paper, organize into folders, and back up to your OWN Google Drive (never our servers - Foldio only sees files it created). Files are plain PDFs you can open anywhere. Free forever; a one-time Pro unlock adds library-wide search, document merging, and PDF import.
