One app, the crime-alert service Citizen, shared personally identifiable information in violation of its published privacy policy.Īnd your iPhone doesn't feed data trackers only while you sleep. IPhone apps I discovered tracking me by passing information to third parties - just while I was asleep - include Microsoft OneDrive, Intuit's Mint, Nike, Spotify, Yelp, The Washington Post and IBM's The Weather Channel. After all, it touted in a recent ad, "What happens on your iPhone stays on your iPhone." My investigation suggests otherwise. You might assume you can count on Apple to sweat all the privacy details.
