About this app

DocuScanr is a private document scanner that keeps your documents on your
device — encrypted, with no account, no cloud upload, no ads, and no
subscription. Ever.

Most scanner apps send your documents to their servers, require a login, bury
you in ads, or charge a subscription forever. DocuScanr does none of that.
Your tax forms, medical records, IDs, and receipts never leave your phone.

Microsoft Lens has been retired. DocuScanr is a private, on-device
replacement: free scanning, no watermarks, no account, and your documents
never leave your phone.

PRIVATE BY DESIGN
• Documents encrypted on your device (AES-256, hardware-backed keys)
• No account, no sign-in, no cloud — your scans can't leave unless you export them
• Zero network traffic in normal use — measured, not just promised
• No ads, no trackers, no watermarks
• Recovery key so you never lose access — without trusting a server
• Optional app lock (PIN / fingerprint) and screenshot protection

SCAN ANYTHING
• Automatic edge detection and perspective correction
• Auto-capture — hold steady and it shoots
• Multi-page documents — combine scans into one PDF, reorder and edit pages
• Import photos and PDFs from your gallery or other apps
• Clean filters: Auto, Color, Grayscale

SEND SENSITIVE DOCUMENTS SAFELY
Scan a tax form, password-protect the PDF, and email it to your accountant —
the exported file is encrypted with a password you set, and the original never
leaves your phone. Fill and sign forms without printing: import a PDF, type
your answers, and place your saved signature. (Pro)

FIND AND ORGANIZE
• On-device text recognition (OCR) — search inside your scans, locally and free
• Folders, rename, and full-text search
• Export as PDF, JPEG, or PNG — with size presets that fit email

PAY ONCE — NO SUBSCRIPTION
DocuScanr is free to use for everyday scanning. A one-time Pro purchase (no
subscription, ever) unlocks batch scanning, the high-contrast B&W filter,
auto-OCR, tags, watermarks, password-protected exports, and more. Buy it once,
own it forever. No trial that quietly converts into a charge, no recurring fee
to remember to cancel.

Pro features:
• Fill and sign — import a PDF form, type into it, add your signature
• Password-protected PDF and ZIP export (AES-256)
• Import password-protected PDFs and encrypted ZIPs
• Batch scanning and multi-select import
• Black & white document filter
• Auto-OCR on save + search across all your documents
• Annotate, sign, and redact
• Tags and watermarks

No subscription. No account. No cloud. No ads. Just a scanner that respects
your privacy.

What’s new

• Importing a PDF now shows how many pages it has and lets you choose which ones to bring in. Grab just the pages you need from a long statement or manual, or import everything with one tap like before. Works with password-protected PDFs too (Pro).
