Privacy-first and on-device processing are no longer niche. A growing cohort of Mac and iOS apps keeps data on-device, trimming cloud chatter while delivering real value. Take Slean—a privacy-focused iOS cleaner where all scanning, duplicate finding, and compression happen on-device; the only online link is RevenueCat for Pro, with optional AI edits. [1]
