Macworld 2010: ScreenGuardz Privacy film keeps prying eyes off your iPhone

David Winograd

NLU Products makes a very large line of screen and computer protection products. I got a chance to speak with Kirk Feller the President and CEO of the company about their newest product ScreenGuardz Privacy (US$19.95), that was released last month at the Consumer Electronics Show.

With the iPhone gaining more functionality seemingly every day through third party apps, privacy has become a concern. I really don't think I want someone looking over my shoulder when I'm doing online banking or reading private email. Kirk told me that there is a large demand for products that not only provide screen protection, but also increase privacy protection.

ScreenGuardz Privacy is a very sturdy screen protector for the iPhone 3G and 3GS. The film used to cover the screen adheres using static electricity making it easy to put on and take off. But there are a lot of screen protectors out there, some offering privacy protection. This does it a bit differently.

Using tiny louvers built into the film, ScreenGuardz Privacy uses four way privacy protection. This means that whether you are using your iPhone in portrait or landscape mode, anyone to your side will see a dark screen. It also helps reduce the amount of light put out by the display which may be distracting in some situations. According to Kirk, other privacy protection products are fine under normal use, but turn the phone to landscape mode and your screen will be visible to any prying eyes. This is the first screen protection product that gives you full privacy protection,

I played with it for a few minutes and it worked exactly as advertised. The iPhone felt just as responsive as ever, but unless you were looking directly at the display, the screen appeared dark and this was true any way I held the device. This is a very simple idea, but the implementation is perfect. It's easy to install, and gives you some peace of mind. For anyone concerned with sensitive data, it seems well worth the price.
