Two articles I just remembered that you might be interested in:
"On your iPhone, you can now tap a button that says, “Ask app not to track.” But behind the scenes, some apps keep snooping anyway.
Say you open the app “
Subway Surfers,” listed as one of the App Store’s “must-play” games. It asks if you’re okay with the app “tracking” you, a question iPhones started displaying in April as
part of a privacy crackdown by Apple. Saying no is supposed to stop apps such as “Subway Surfers” and Facebook from learning about what you do in other apps and websites.
But something curious happens after you ask not to be tracked, according to an
investigation by researchers at privacy software maker
Lockdown and The Washington Post. “Subway Surfers” starts sending an outside ad company called
Chartboost 29 very specific data points about your iPhone, including your Internet address, your free storage, your current volume level (to 3 decimal points) and even your battery level (to 15 decimal points). It’s the kind of unique data that could be used by advertisers to identify your iPhone, possibly letting them know what other apps you use or how to target you."
To test Apple’s newest privacy protections, we watched the data flow out of 10 popular apps. Some appeared to be “fingerprinting” phones, a more invasive form of tracking.

"It’s 3 a.m. Do you know what your iPhone is doing?
Mine has been alarmingly busy. Even though the screen is off and I’m snoring, apps are beaming out lots of information about me to companies I’ve never heard of. Your iPhone probably is doing the same — and Apple could be doing more to stop it.
On a recent Monday night, a dozen marketing companies, research firms and other personal data guzzlers got reports from my iPhone. At 11:43 p.m., a company called Amplitude learned my phone number, email and exact location. At 3:58 a.m., another called Appboy got a digital fingerprint of my phone. At 6:25 a.m., a tracker called Demdex received a way to identify my phone and sent back a list of other trackers to pair up with.
And all night long, there was some startling behavior by a household name: Yelp. It was receiving a message that included my IP address -— once every five minutes."
We ran a privacy experiment to see how many hidden trackers are running from the apps on our iPhone. The tally is astounding.
