Sumi - Redact & Blur Photos

Sumi finds and hides private information in your screenshots — automatically, before you share them. Pick a photo and Sumi instantly detects what shouldn't be shared: faces, email addresses, phone numbers, URLs, street addresses, credit card numbers, prices, QR codes, and other sensitive numbers. Choose mosaic, blur, or ink blackout, then save or share. Done in seconds. WHY SUMI - AUTOMATIC DETECTION Faces and personal info are found for you. Tap any box to toggle it, or tap a category chip to toggle a whole category at once. - MY KEYWORDS Register your own name, company, or ID once — Sumi finds and masks it in every screenshot, even when the text is spaced or slightly misread. - REDACT MULTIPLE PHOTOS Select up to 20 screenshots and mask them all in one go. Tap any photo to fine-tune it. - SHARE EXTENSION Redact directly from the share sheet of any app — no need to open Sumi first. - PEN TOOL Draw over anything the detector missed. Three mask styles: mosaic, blur, and sumi-ink blackout. - 100% PRIVATE BY DESIGN Everything runs on your device. No network connection, no ads, no analytics, no tracking. Saved images contain no EXIF or GPS metadata. - PAY ONCE No subscription. No watermark. No locked features. Buy once, use forever. Sumi (墨) is Japanese ink — the app is named after "sumi-keshi," the traditional art of blacking out text.
