Is cxense.com Safe?

From their Linked-In entry: "Using audience data and advanced real-time analytics, Cxense creates hyper-relevant content recommendations, targeted advertising and predictive search that help increase digital revenue for publishers and e-commerce businesses, and provide users with a better experience. By capitalizing on data to match user preferences and create unprecedented personalization online, companies gain more engaged and loyal users, higher advertising revenue and increased digital subscribership." ***** In order to pull that off, they would have to track individuals with a high-level of fidelity. Not the worst offense in the world, but not a joyful one either.
