Apple removes Facebook's Onavo security app from the App Store -- CNBC

For more Onavo details, see this Wikipedia article

"Facebook acquired Israel-based Onavo in 2013, snapping up the free security app that lets users access a virtual private network, or VPN, to browse the web and download apps with a greater degree of privacy. Facebook in the past has offered that service to users without clearly disclosing that it owns the app, and has collected data about what other types of apps those customers use.

In June, Facebook told Congress that it does not use Onavo data "for Facebook product uses" or to collect information about individuals, but it has admitted to using Onavo to gather broad information about which apps are popular and how people are using them, which it uses to improve its own products."
