PurePaper - Minimalist Scanner
宇航 吴
PurePaper is a high-end document scanning tool for people who value aesthetics and efficiency. A tool should stay out of the way—it shouldn’t track you, require a subscription, or upload your private documents to someone else’s server. [CORE FEATURES] The “Flatbed Look”: Adaptive shadow removal clears uneven lighting and restores a clean white background. Precision warping: System document edge detection and perspective correction straighten skewed photos into rectangular pages. Text sharpening: Boosts contrast for handwriting, stamps, and print. Four core modes: Magic Color, Flatbed Look, B&W Document, and Original Photo. On-device OCR & full-text search: Chinese (Simplified/Traditional), English, Japanese, German; search titles and page content from Home. Searchable PDF: Optional invisible text layer. Enabled by default for PDF export; disable in Export for image-only PDFs. Sign, annotate & redact: PencilKit markup; redact sensitive text automatically or by hand. Tags & merge: Colored tags; merge multiple documents into one multi-page file. App Lock: On by default. Face ID, Touch ID, or device passcode is required on launch and when returning from the background. To turn it off: Settings → App Lock → disable “Require Face ID / Passcode”. [OPTIONAL — OFF BY DEFAULT] Backup Destination: Settings → Backup Destination. Default is Local Only. Switch to iCloud Drive or your own WebDAV server to back up exports. [WHY PUREPAPER?] Ultra-minimal native UI—no clutter, just scanning. Anti-subscription: one-time purchase, lifetime ownership. Native Swift stack for fast launch and processing.
