About this app

ScanHarbor is a document scanner built for privacy. Every page you scan is encrypted on your device the moment it's captured — no account required, no cloud upload, no tracking.

Why ScanHarbor?

Most document scanner apps send your scans to the cloud for processing. ScanHarbor does everything on your device. Your documents never leave your phone.

SCAN & EXPORT
• Scan single pages or multi-page documents in seconds
• Auto-detect document edges and apply perspective correction
• Export to PDF or share individual pages as images
• Enhancement modes: Magic, Grayscale, Original

PRIVACY & SECURITY
• AES-256-GCM encryption — every scan, thumbnail, and PDF is encrypted at rest using a key stored in your device's secure hardware (Android Keystore)
• Biometric app lock — require fingerprint, face unlock, or device PIN to open the app
• No account required — ScanHarbor never asks you to sign in
• No cloud sync — your documents stay on your device, always
• No ads, no analytics, no tracking

SEARCH
• Semantic search powered by an on-device AI model (MiniLM)
• Search by meaning, not just exact keywords — find "rental agreement" even if you typed "lease contract"
• All indexing runs locally — your document content is never sent anywhere

ORGANIZE
• Create color-coded folders to keep documents sorted
• Rename, merge, and split documents
• Set expiry dates on documents that should be reviewed or deleted

ScanHarbor PRO
Upgrade to Pro to unlock:
• Vault backup & restore — export a passphrase-protected encrypted backup of your entire vault and restore it anytime

PERMISSIONS
• Camera — required for scanning
• Biometrics — optional, used only for the app lock you control

ScanHarbor does not request internet, contacts, microphone, or location permissions.

ScanHarbor is the document scanner for people who handle sensitive paperwork — medical records, tax documents, legal contracts, financial statements — and don't want that content sitting on someone else's server.

Scan privately. Stay in control.
