Other apps flag your vacation photos as sensitive. NuDefndr never does.
Apple's SensitiveContentAnalysis framework delivers industry-leading accuracy. If sensitive content exists, NuDefndr is highly likely to detect it.
Your beach photos, medical images, and art won't get flagged. The ML model is trained for precision—not paranoia.
~1 second per photo on modern devices (A15+). Large libraries may take time, but accuracy is never compromised for speed. Every photo gets the full analysis it deserves.

Technicians need your passcode? Secure sensitive photos before handing over your unlocked device.
Family members use your iPad? Keep your personal photos separate and secure.
Photos you're not ready to delete but shouldn't be in your daily camera roll.
