Redact hides personal details in screenshots, photos and PDFs before you share them. It reads the page on your iPhone, outlines phone numbers, emails, ID, card and account numbers, and lets you cover them in a tap. Nothing is uploaded, ever. FINDS IT FOR YOU • An on-device scan reads English, Malay and Chinese text, down to the fine print • Spots emails, phone numbers, links, addresses, ID numbers, card and account numbers, license plates and labeled names • Review the list, uncheck false alarms and redact the rest, or tap any outline to cover just that one • Nothing is covered until you say so HIDES IT PROPERLY • Solid black redaction boxes • Blur and pixelate that can't be guessed back. Ordinary blur smudges the hidden text itself, so it can be matched. Redact swaps the inside of the box for a nearby patch of the picture first, so nothing of the original is left • Tap a line of text to cover exactly that line • Low, Medium or High intensity for blur and pixelate • Highlight, underline, strike through, draw and add text • Undo and redo every step MARKS A COPY FOR ONE USE • Write "For tenancy application only", or any purpose, across every page of a copy • Handy when a landlord, employer or agency asks for a copy of your ID, payslip or bank statement: the marked copy can't be reused for anything else • The mark comes in 15 languages, picked from your phone's language SHARES ONLY WHAT YOU MEAN TO • The export review shows exactly what will be shared and flags detected items nobody has checked • Every export is a flattened copy: hidden content is gone, not just layered on top • Location and camera details are removed from exported images, and PDF creation details are wiped • Your original is never changed • Save to Photos or share to any app WORKS WITH • Photos, the camera, Files and PDFs • Join several screenshots of a long chat or receipt into one image, then hide what's private • iPhone and iPad PRIVATE BY DESIGN • Everything happens on your device. Redact has no server and works offline • No account, no ads, no analytics, no tracking • Open documents are hidden from the App Switcher Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
