Honestly, this sounds like the South Korean governments version of Superfish: "Parents will be able to to see what their kids are up to online and block access to "undesirable" sites." Given any number of browsers could be installed on the phone, I'm thinking there's a high likelihood this could be a proxy based solution since that would be the simplest approach. While such approaches to nanny guards aren't necessarily inherently broken, there are some real-world difficulties that make the design and implementation hard to secure. I hope they had a really good security review.
