ScanLocker: Document Scanner

ScanLocker is a fast, private document scanner that turns paper into clean, searchable PDFs. Point your camera at any page — it finds the edges, crops, straightens and enhances the scan, then saves a PDF you can search, lock and share.

Scan receipts, invoices, contracts, IDs, business cards, notes, whiteboards and multi-page reports. Everything runs on your phone: no account, no uploads.

FREE AND PRO
Scanning, enhancement, PDF export, OCR and password protection are free. ScanLocker Pro is an optional subscription (monthly, yearly or lifetime) that removes ads, lifts folder limits and unlocks unlimited searchable exports. The free version is supported by ads; a rewarded ad can unlock one Pro action up to three times a day. Pro users see no ads at all. Buy, restore or cancel any time from your store account.

Scans never leave your phone unless you tap Share. Ads are served by Google AdMob and measured by Firebase Analytics and Crashlytics only after you accept the in-app consent form; if you decline, no ad is requested. No document content, OCR text or file names are collected. Full policy: https://prodevinfotech.github.io/scanlocker-legal/
