PocketScan
Privacy-First Document Scanner · v0.5.0
Camera-based document scanner that stays on your phone. Capture multi-page docs in batch mode, crop with draggable corners + pinch-to-zoom review, sign with reusable stamps, redact sensitive bits with black rectangles, export as password-protected PDFs with watermark, and LAN-share via AirBridge. Library is folder-organised and PIN-locked. No cloud, no telemetry, no account, no Play Store. PocketScan is the small, fast, fully on-device alternative to CamScanner (banned in India 2020) and Adobe Scan (bloated + cloud-default). On-device PaddleOCR text recognition and OpenCV NDK auto-corner detection land in v0.6/v0.7.
