What is Just Scan?
Just Scan is a lightning-fast, privacy-first Android document scanner designed to scan receipts, contracts, books, and multi-page documents into clean, searchable PDFs—without subscriptions, cloud uploads, ads, or tracking.
Built with a strict 100% on-device philosophy, all document edge-detection, perspective correction, optical character recognition (OCR), and biometric encryption happen entirely on your phone's local processor. Your personal documents never leave your device.
What Does It Do?
Smart Optical Capture & Edge Detection
Uses Google’s machine-learning scanner engine to automatically detect paper edges, flatten curved pages, remove shadows, and eliminate finger marks. Users can manually fine-tune crop corners and borders using a magnifying loupe tool.
On-Device Searchable PDFs (OCR)
Instantly extracts text from every scanned page directly on your device. Find any document in seconds by searching for words, invoice numbers, or names contained inside the scanned text.
Sequential PDF Compiler & 0-Byte Cache Enforcement
Unlike other scanners that secretly bloat phone storage with gigabytes of leftover temporary images, Just Scan uses sequential bitmap streaming and enforces an automated 0-byte cache cleanup after every scan.
Biometric Vault & Locked Folders
Allows users to organize scans into custom folders (e.g., Receipts, Taxes, Medical) and lock sensitive folders behind Android’s hardware-backed Fingerprint & Face Unlock.
Flexible Export Presets
Choose between Compact (< 800 KB, perfect for email and messaging) and Archive (300+ DPI, crystal-clear archival quality for legal documents and contracts).
Built-in Offline PDF Viewer & Sharing
Preview, swipe through pages, and share documents directly through the native Android system share sheet to Google Drive, email, or messaging apps of your choice.
