Apple Responds to Location Tracking Controversy: “We Don’t Track Your iPhone”

By , Apr 27, 2011

Apple has decided to officially respond to the iPhone’s location database issue that has been undergoing intense scrutiny by the media and industry experts. In a Q&A response, Apple has addressed why the iPhone logs your location, and what Apple does with that information.

An alleged email from Steve Jobs answered this issue already with a simple response: “We don’t track anyone.” That’s the message that Apple is confirming with this Q&A response

1. Why is Apple tracking the location of my iPhone?
Apple is not tracking the location of your iPhone. Apple has never done so and has no plans to ever do so.

2. Then why is everyone so concerned about this?
Providing mobile users with fast and accurate location information while preserving their security and privacy has raised some very complex technical issues which are hard to communicate in a soundbite. Users are confused, partly because the creators of this new technology (including Apple) have not provided enough education about these issues to date.

3. Why is my iPhone logging my location?
The iPhone is not logging your location. Rather, it’s maintaining a database of Wi-Fi hotspots and cell towers around your current location, some of which may be located more than one hundred miles away from your iPhone, to help your iPhone rapidly and accurately calculate its location when requested. Calculating a phone’s location using just GPS satellite data can take up to several minutes. iPhone can reduce this time to just a few seconds by using Wi-Fi hotspot and cell tower data to quickly find GPS satellites, and even triangulate its location using just Wi-Fi hotspot and cell tower data when GPS is not available (such as indoors or in basements). These calculations are performed live on the iPhone using a crowd-sourced database of Wi-Fi hotspot and cell tower data that is generated by tens of millions of iPhones sending the geo-tagged locations of nearby Wi-Fi hotspots and cell towers in an anonymous and encrypted form to Apple.

4. Is this crowd-sourced database stored on the iPhone?
The entire crowd-sourced database is too big to store on an iPhone, so we download an appropriate subset (cache) onto each iPhone. This cache is protected but not encrypted, and is backed up in iTunes whenever you back up your iPhone. The backup is encrypted or not, depending on the user settings in iTunes. The location data that researchers are seeing on the iPhone is not the past or present location of the iPhone, but rather the locations of Wi-Fi hotspots and cell towers surrounding the iPhone’s location, which can be more than one hundred miles away from the iPhone. We plan to cease backing up this cache in a software update coming soon (see Software Update section below).

5. Can Apple locate me based on my geo-tagged Wi-Fi hotspot and cell tower data?
No. This data is sent to Apple in an anonymous and encrypted form. Apple cannot identify the source of this data.

6. People have identified up to a year’s worth of location data being stored on the iPhone. Why does my iPhone need so much data in order to assist it in finding my location today?
This data is not the iPhone’s location data—it is a subset (cache) of the crowd-sourced Wi-Fi hotspot and cell tower database which is downloaded from Apple into the iPhone to assist the iPhone in rapidly and accurately calculating location. The reason the iPhone stores so much data is a bug we uncovered and plan to fix shortly (see Software Update section below). We don’t think the iPhone needs to store more than seven days of this data.

7. When I turn off Location Services, why does my iPhone sometimes continue updating its Wi-Fi and cell tower data from Apple’s crowd-sourced database?
It shouldn’t. This is a bug, which we plan to fix shortly (see Software Update section below).

8. What other location data is Apple collecting from the iPhone besides crowd-sourced Wi-Fi hotspot and cell tower data?
Apple is now collecting anonymous traffic data to build a crowd-sourced traffic database with the goal of providing iPhone users an improved traffic service in the next couple of years.

9. Does Apple currently provide any data collected from iPhones to third parties?
We provide anonymous crash logs from users that have opted in to third-party developers to help them debug their apps. Our iAds advertising system can use location as a factor in targeting ads. Location is not shared with any third party or ad unless the user explicitly approves giving the current location to the current ad (for example, to request the ad locate the Target store nearest them).

10. Does Apple believe that personal information security and privacy are important?
Yes, we strongly do. For example, iPhone was the first to ask users to give their permission for each and every app that wanted to use location. Apple will continue to be one of the leaders in strengthening personal information security and privacy.

Software Update
Sometime in the next few weeks Apple will release a free iOS software update that:

  • reduces the size of the crowd-sourced Wi-Fi hotspot and cell tower database cached on the iPhone,
  • ceases backing up this cache, and
  • deletes this cache entirely when Location Services is turned off.

In the next major iOS software release the cache will also be encrypted on the iPhone.

Apple isn’t using the iPhone’s GPS to “track” anything. The location database is based off Wi-Fi hotspots and cell towers around you, and that information is used to help the iPhone calculate your coordinates more quickly. Any location information sent to Apple is encrypted and anonymous.

Apple does admit that the database shouldn’t be logging so much of your location history. As expected, that’s a bug that Apple plans to fix in an upcoming update to iOS.

The Q&A states that the iPhone only needs to store about seven days of location data for accurate results. They also plan on encrypting the locally stored database file on your computer so that it cannot be accessed by programs like iPhone Tracker.

Has Apple helped ease your concern about this issue? Was it something you were even worried about? Perhaps the media should stop focusing on what Apple does with location data and think about what Google, carriers, and third parties could be doing with device location data.

    Short version is new update. Save your blobs. :)

      Theyre lying. The files have already been found and theyre just trying to make it sound like some kind if accident because they know it is illegal. They already have government officials and lawsuits taking aim at them over this. But it’s nothing a few millions dollars can’t buy them out of.

      Fuck apple. They want you to own an apple product so they can own you and all your personal info including exactly where you are.

        “they’re lying”…

        You’ve totally convinced me dude. Totally.

  • JoeJustice

    @ James – lol, yep! hehe
    I’m glad they are addressing it at Apple’s end. But like you said, maybe the concern right now should be how 3rd parties are able to access the data.
    Seems to be a TOTAL invasion of privacy WITHOUT a warrant for cops to hook up your phone to a gadget and pull ALL your personal data from it.
    Anyway, glad to see it being addressed.
    AND I have my blobs saved. ;)

    Yeah, Yeah, Yeah… time to move on. To many alarmist going bat crazy over nothing AGAIN!

      Apple OWNS you!

    See, it’s nothing at all to be worried about let’s all get back to our daily lives and back to the iPhone 5 rumors. To all the paranoids, keep on tokin’

    “2. Then why is everyone so concerned about this?” excuse me, not everyone, I certainly wasn’t bothered or concerned about this. as I’ve said before, plantbeing’s Signal app from last august displays current and ‘visited’ cell tower locations on a map and my guess is this ‘secret’ cache was possibly used in some way to collate that data. now, let’s move on… :)

  • JoBerlin

    Apple is so bad right now because they are SENDING that data to the iPhone. So the iPhone can calculate it’s position for Google Latitude and will UPLOAD your position to Google. It’s OK that Google tracks you because Google’s motto is: “Don’t be evil!”
    Or use your position to check in everywhere you go. Mark Zuckerberg won’t use that data for bad stuff. He runs a social network. And things that are social can’t be bad, right?
