About this app

Foldio is a PDF scanner and personal document library for Android — scan, organise into folders, and back up to your OWN Google Drive. No subscription, no ads, no account.

Build a library you actually own: every scan is saved as an ordinary PDF, kept on your device, and (optionally) mirrored to your own Google Drive — never to Foldio's servers. Open your files on any device, in any app. Nothing is locked in.

If you're looking for a Microsoft Lens alternative or a CamScanner replacement that doesn't charge monthly, this is it.

📚 YOUR PERSONAL PDF LIBRARY
• Organise scans into folders and filter your library with one tap
• Move documents between folders anytime
• Back up to your own Google Drive — your folder structure mirrors automatically
• Files land as standard PDFs you can open anywhere — no proprietary format, no lock-in
• Foldio uses a restricted Drive permission: it can only see the files it created, never the rest of your Drive

📄 SCAN & IMPORT
• Scan paper documents with ML Kit's edge-detection scanner — automatic crop and straighten
• Import existing PDFs directly from any app ("Open with Foldio")
• Add pages to any document at any time

✏️ EDIT & ANNOTATE
• Sign documents with your own handwritten signature
• Add text labels and colour highlights to any page — drag and resize to position exactly
• Crop, rotate, adjust brightness and contrast per page
• Magic Enhance — one tap auto-optimises colour and contrast
• Reorder pages with drag-and-drop

📤 EXPORT & SHARE
• Export as PDF with searchable text layer — OCR text is embedded so you can copy and search in any PDF reader
• Export as plain text
• Share to WhatsApp, email, Files, or any app
• Print directly from the app

🔍 QUICK ACCESS
• Long-press the Foldio icon to reveal a "Scan" shortcut
• Drag it to your home screen for one-tap scanning from anywhere

🔐 PRIVACY FIRST — NO COMPROMISES
• All scanning and OCR runs on-device — no cloud AI, no tracking, no analytics
• Foldio never accesses your camera directly — it runs inside Google ML Kit's own activity
• Internet is used only if you enable Google Drive backup — and then files go straight to your account
• No Foldio account needed, ever
