PDFly finds the PDFs on your phone, locks them behind a PIN, and lets you read, highlight, sign and reorganise them — entirely offline. No account, no uploads, no tracking. Your documents never leave your device.
Screenshots from the current build are on their way. Meanwhile, here’s the face of PDFly.

A 4- or 6-digit PIN, optional fingerprint unlock, auto-lock in the background, and growing lock-outs after wrong attempts.
No account and no uploads. Your files, marks and signatures stay on your phone — PDFly itself never opens a connection.
Pick folders, or scan the whole phone. Grid or list, seven sorts, filters, page-one thumbnails, and “Open with” from any app.
Picks up where you stopped. Search inside the PDF, bookmarks, night mode, go to page, and password-protected files.
Highlight along the text, draw, add shapes, arrows, text and stamps — in seven colours, solid or see-through. Undo and redo every step.
Sign on the screen or import a picture of your signature. Keep up to five, behind the PIN, ready for any document.
Reorder, turn and remove pages, merge PDFs together, or extract just the pages you need into a new file.
Your marks live in PDFly. “Save as new PDF” writes a fresh copy with them in it — the original file is never changed.
Cover text with a solid box and it is genuinely removed from the saved copy — not just hidden under a shape.
Choose a 4- or 6-digit PIN and, if you like, turn on fingerprint unlock. PDFly can lock itself whenever you step away.
Pick the folders PDFly should look in, or let it scan the whole phone. Your library appears with thumbnails, ready to sort.
Read freely, try every editing tool, and save a marked-up copy, an extract, or a merged PDF when you’re ready.
The editor pass is one payment for one year, through Google Play. It never renews by itself.
The current price of the editor pass is shown in the app and on Google Play.
