OneScan is a fast, private document scanner for iPhone and iPad. Scan receipts, forms, paper notes, and multi-page documents with Apple's document camera, or import photos. New and existing scans are automatically recognized on your device, so you can search names and the words inside your documents. Name each scan, keep it in your local Recent list, reopen it later, and export PDF, JPEG, PNG, or compact PDFs when you are ready. OneScan is privacy-first: no account, no ads, no third-party tracking, and no document upload. Recent scans stay on this device until you delete them. Limited first-party product analytics is sent only after you choose to share it. It uses a random app-scoped identifier and never includes documents, images, recognized text, or file names. You can turn it off or reset the identifier in Settings. Scanning, automatic text recognition for in-app search, common export formats, and basic PDF compression are free. OneScan Pro is a one-time purchase that unlocks text copying, searchable PDFs, target-size compression, page tools, smart names, privacy masks, and Face ID library lock.
