Tribble is one of three "policy czars" at Apple (along with Jane Horvath and Erik Neuenschwander) who spends a significant amount of time on privacy. Any collection of Apple customer data requires sign-off from a committee of the three privacy czars and a top executive, according to four former employees of Apple who worked on a variety of products that went through privacy vetting.
