## What is Duna's AI Scanner?

Duna AI Scan is the fastest, most private way to scan and organize your documents on iPhone.

Point your camera, capture, done. Built-in AI auto-detects edges, removes shadows, sharpens text, and runs OCR locally — without uploading anything to a server.

WHY DUNA
• Lightning-fast capture with auto edge detection and perspective correction
• Import existing photos from your library — same Magic Filter & OCR as a fresh capture
• Add pages to any document later, from the camera or your photo library
• Magic Filter v2 with shadow removal — clean scans even under uneven lighting
• On-device OCR (text recognition) in English and Vietnamese
• Smart auto-tagging: invoices, receipts, ID cards, contracts, business cards
• Auto-extract key fields: vendor, total amount, date, tax ID, due date, notes
• Multi-page documents with reorder, rotate, crop, and re-shoot per page
• PDF export, deterministic file naming, and clean folder organization

PRIVATE VAULT
• Tap to lock any document with AES-256-GCM encryption
• Unlock with Face ID, Touch ID, or your own passphrase
• Blurred thumbnails so sensitive docs never preview accidentally
• Anti-screenshot redaction on the lock screen
• Encryption keys stored in iCloud Keychain — your private documents follow you across devices, encrypted end-to-end

ZERO BACKEND, FULL SYNC
• Documents sync via your own iCloud account (CloudKit Private Database)
• Nothing ever touches our servers
• Sign in with Apple — no email, no password, no tracking

BUILT FOR PROFESSIONALS
• Send any document JSON payload to your own webhook (Gateway tab in Settings)
• Deterministic JSON Schema v1 — perfect for accounting and ERP automation
• Future-ready for team workflows and BizConnex integration

PRIVACY FIRST
• OCR runs entirely on-device using Apple's Vision framework
• AI extraction uses Apple Intelligence (on supported devices) — never leaves your iPhone
• No analytics, no third-party tracking SDKs, no behavior profiling
• Banner ads are clearly labeled and respect App Tracking Transparency

ACCESSIBILITY
• Dynamic Type
• Full VoiceOver support on all primary screens
• Reduce Motion respected

REQUIREMENTS
• iPhone running iOS 17 or later
• iCloud account (optional, for sync)
• Apple Intelligence (optional, for advanced field extraction on iPhone 15 Pro and newer)
