There's a steep price to pay for jumping into the Oculus Rift virtual reality world.
"Please note that no data transmission or storage can be guaranteed to be 100% secure.

Hong Kong-based toymaker VTech, which last year was hacked leaving millions of child and parent data exposed, was criticized for including similar language in its new terms of service, following the recovery of its systems.
Given how much data the company collects on its users, such a policy could be problematic.
The policy says it will collect identifiable information, such as your IP address and other device identifiers to determine who you are, along with your GPS location and other data. But it goes a step further by saying the company will also collect "information about your physical movements and dimensions when you use a virtual reality headset."
What's Oculus doing with that data? It's handing it to Facebook, which uses it for advertising.
"We use the information we collect to send you promotional messages and content and otherwise market to you on and off our Services. We also use this information to measure how users respond to our marketing efforts."
Put the identifiable information together and you've got a system that allows Facebook to uniquely identify users on individual devices and build up advertising profiles.
And not just that: the data will be shared with Facebook's "related companies," such as WhatsApp, Instagram, but also its marketing and advertising companies, LiveRail and Atlas.
Facebook makes more than 95 percent of its revenue from advertising, so it's not all that surprising that the company is aiming to expand that effort. The virtual reality device is always on, so it's collecting data even when you're not using it. That leaves open the possibility of abuse.
And if at any point Oculus or Facebook doesn't like what users are doing with its service, it can cut off its users, for any given reason -- effectively turning your $599 virtual reality headset into an expensive paperweight.
