Your documents never leave your phone. Point your camera, and paper becomes a clean PDF that is never uploaded to anyone. Don't believe it? Turn on airplane mode and watch Scanner keep working — because nothing is ever sent anywhere. That's the difference from the other scanners: your IDs, contracts, medical forms and receipts stay private, because they physically never leave the device. No watermark on the output. No account to create. No ads. No subscription nag. WHY BARO BEATS THE OTHER SCANNERS • Nothing uploaded — works fully in airplane mode, verify it yourself. • No watermark stamped on your PDF. Ever. • No account, no sign-in, no email harvesting. • No ads, no subscription, no surprise paywall. WHAT IT DOES • Scan anything — live edge detection and perspective correction capture a crisp, straightened page: receipts, contracts, IDs, notes, forms, mail. • Import photos — already have the shot? Turn photos on your phone into the same clean PDF, without opening the camera. • Multi-page PDFs — add as many pages as you need and save them as one clean PDF. Reorder, retake or remove a page with a single tap. • Color, Grayscale or Black & White — pick the look that makes text sharpest and keeps files small. • Local library — every scan lives only on this phone. Open, rename, share or delete. No cloud, no sync. • Lock your documents — put Face ID, Touch ID or your passcode in front of your library. Off by default, and the check happens entirely on this phone: the app only ever gets a yes or a no. • Share anywhere — send your PDF to Mail, Messages, Notes or any app in one tap, straight from the save confirmation. PRIVACY YOU CAN VERIFY Zero analytics. Zero telemetry. Zero third-party SDKs. No network code at all. Turn on airplane mode and scan — everything still works, because nothing is ever sent anywhere. The privacy label says "Data Not Collected," and you can prove it. HONEST ABOUT WHAT IT IS Scanner makes sharp image PDFs. It does not add a searchable OCR text layer yet, and there is no cloud backup or sync — both are intentionally absent, not coming "for a fee." Imported photos get the filters and the PDF, but not the edge detection and perspective correction — those happen at capture time, in the camera. We'd rather promise less and keep every promise. MADE TO BE EASY Every button is large and easy to hit. High-contrast AMOLED dark screen. Big, bold text. No double-taps, no hidden gestures — just Scan and Library. MADE FOR Anyone scanning an ID, a signed contract or a medical form who refuses to upload it. Receipts and expense reports. Student notes and handouts. Anyone who values privacy, simplicity and no watermarks. NO SUBSCRIPTION No subscriptions, no in-app purchases, no ads, no account. That's the whole deal. Part of the Baro family — The tools you reach for first.
