About this app

Your PDFs are yours. FoldPine never uploads them anywhere — because it has nowhere to upload them to.

Most PDF tools on the web and in app stores send your documents to a server to process them, meter you to a couple of tasks per day, and charge to remove the limits. FoldPine does the work on your phone, does it for free, and doesn't count.

EVERYTHING IS FREE
• No daily task limits, no file-size caps
• No watermarks on anything
• No subscription, no account, no ads, ever

WHAT IT DOES
• MERGE — combine two or more PDFs into one, in the order you choose
• SPLIT & EXTRACT — pull out pages ("1-3,7") or split every page into its own file
• ORGANIZE — reorder, rotate and delete pages with a thumbnail grid
• IMAGES → PDF — turn photos into a clean A4 PDF
• PASSWORD — protect a PDF with a password, or remove one you know

NOTHING LEAVES YOUR PHONE
Files are opened through Android's own file picker, processed on your device, and saved only where you choose. Tax documents, contracts, medical records — none of it touches a server. There is no analytics code and no way for the app to phone home; the only network use is Google Play's own billing, and only if you choose to leave a tip.

BUILT FOR REAL FILES
Large documents are handled with care — work is streamed through temporary files so hundred-page PDFs don't choke your phone, and if an operation fails nothing partial is ever written over your files.

HONEST ABOUT WHAT IT ISN'T
FoldPine organizes pages; it doesn't change the text inside them. If a PDF is damaged, it tells you plainly instead of pretending.

If FoldPine saves you from yet another "3 free tasks per day" wall, there's an optional tip jar in Settings. Tipping is never required — every feature is already yours.

FoldPine is built on Apache PDFBox (Apache License 2.0).
