ScanHarbor: Private Scanner

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.

Looking for a Microsoft Lens replacement?

Lens is gone, and its replacement saves your scans to the cloud. ScanHarbor keeps them on your phone, encrypted, and lets you save PDFs to any folder you choose. No sign-in, no watermarks, no monthly scan limits.

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 unless you share them.

SCAN & EXPORT
• Scan documents in seconds with automatic edge detection and perspective correction
• ID card mode — scan the front and back of a license, insurance card, or ID onto a single page at real size, ready to print or send
• Save PDFs straight to any folder on your phone, or share them as PDF or JPEG
• Enhancement modes: Magic, Black & White, Grayscale, Original
• No watermarks on your scans. No limit on how many you make.

SMART NAMING
• Scans name themselves. ScanHarbor reads the page on your device and suggests names like "Invoice – Acme Plumbing – Mar 2026" or "Driver's license – State of Ohio" instead of "Scan 0042"
• Rename anything, anytime

SEARCH
• Semantic search — find documents by meaning, not just exact words. Search "proof of income" and surface your pay stubs and tax returns even if those words never appear in the title
• Powered by an on-device AI model (MiniLM) — no server, no API call, no data leaving your phone
• Combines keyword and semantic results so you always find what you're looking for

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
• Custom ScanHarbor passcode — set a 4–6 digit passcode separate from your device PIN; biometrics remain available as a quick shortcut
• 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

PERMISSIONS
ScanHarbor doesn't even ask for camera permission. Scanning runs through Google's secure document scanner, which hands the app only the pages you choose to keep.
• Notifications — optional, only for the expiry reminders you set

ScanHarbor does not request internet, camera, contacts, microphone, location, or storage 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.
