The Journal‘s report lays bare much of what we already suspected, or outright knew but didn’t bother thinking about: iOS and Android apps are having a field day with your personal info. More than half of the 101 popular apps they tested sent your UDID to companies without your awareness or consent. Nearly as many sent your location, and a handful even sent along demographic info and other personal details to advertisers.
It’s a small sample size given the hundreds of thousands of apps out there, but it’s hard to imagine that the most prominent names just happen to be the most aberrant. And the list of worst offenders also reads like a roll-call of must haves: Pandora. Angry Birds. Netflix. Shazam. Et tu, Yelp?
Also something very interesting
iOS apps shared more data than Android apps, on the whole—somewhat surprising given the rigidity of the App Store approval process compared to Android’s looser environment. And there’s really nothing you can do to stop it.
So just because your App store is curated doesn’t mean squat. Companies get a free reign on your data anyway.
