## Full description

Sumi reads a PDF or scan, flags personal data it finds, and lets you keep, remove or add to each item before anything is applied. The download is rebuilt as page images with the black boxes painted into the pixels, so no text layer, fonts or metadata remain to copy. Scanned pages and photos are read on the device in 30 languages, and an optional AI model that spots names the rules miss downloads once and then runs offline.
