The Nillkin Guardian Full Privacy is a protective screen shield designed specifically for the iPhone 17 to keep your personal data hidden from prying eyes. It utilizes a specialized privacy filter that limits the viewing angle to 28°, ensuring that the display remains visible only to you while appearing dark to anyone looking from the side. Crafted from AGC Japanese high-aluminum glass with a 9H hardness rating, this 0.33mm thick protector guards your screen against impacts and scratches. The 2.5D curved edges prevent chipping and blend smoothly with the phone's design, while an oleophobic coating and anti-glare finish keep the surface free from fingerprints and grease. To make the application process effortless, the package includes a vacuum alignment frame that automatically positions the glass for a precise, bubble-free fit.
