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, ID cards, and receipts never leave your phone.

Microsoft Lens has been retired. If you are looking for a Microsoft Lens alternative, 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

WORKS OFFLINE
DocuScanr is an offline document scanner. Scanning, filters, OCR, and export all run on your phone, with no internet connection required. Scan documents offline on a plane, at the cabin, or anywhere without signal; nothing waits on an upload, because nothing is uploaded.

SCAN ANYTHING TO PDF
• Scan to PDF in seconds: automatic edge detection and perspective correction
• Auto-capture: hold steady and it shoots
• Scan receipts, ID cards, contracts, letters, and whiteboards
• 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)

MADE FOR REAL PAPERWORK
Scan documents to PDF for taxes, insurance claims, school forms, and expense reports. Digitize a filing cabinet one folder at a time, keep a secure document scanner in your pocket for new mail, and find old receipts by their text when you need them again.

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

Whether you need a receipt scanner for expense reports, a private PDF scanner for contracts, or a document scanner app for the family paperwork drawer, DocuScanr handles it without ever phoning home.

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

What’s new

• The camera now spots your page faster and more often, including plain white sheets on a wooden desk, handwritten pages and boxes.
• Once your page is found, its outline no longer flickers off while you hold the phone still, so auto-capture isn't interrupted.
The new page detector works fully offline. Everything stays on your device.
