back to article iPhones secretly track 'scary amount' of your movements

Apple's iPhone and iPad constantly track users' physical location and store the data in unencrypted files that can be read by anyone with physical access to the device, computer researchers said. The file, which is stored on both the iOS device and any computers that store backups of its data, can be used to reconstruct a …

    ...exactly WHO is surprised about this...

    1. PerfectBlue


      To be honest, I'd taken it for granted that most smart phones did this.

      In the US the Feds mandate that all US cell phone have lojack capabilities so that the cops can track you. It's actually written into the rules. So the fact that Apple records them comes as no surprise to me.

      1. Steve Evans


        There is a bit of a difference in being able to ask a phone to remotely tell you of its location when it has been lost/stolen (as is done with MobileMe on the iphone and countless applications on Android including "Where's My droid" and "Lookout") and having a device "pre-emptively" recording your every move and recording it for month after month without any permission requested or granted!

        Would you say "OK" to an a new application that said it would record all your movements and store them in an unencrypted file when you backup? I certainly wouldn't.

        Whilst there are reasons to need to know the current location, there are no reasons I can see that would require this to be stored in a historical log. I'm sure the security services could find lots of reasons this is a good idea, but then they aren't interested in your privacy.

        It does sound like a bit of debugging code which has been left in, but whatever the reason, it's not a nice discovery.

          Didn't you read evreyword in the 16000 word EULA it clearly gives them permission to track you and share this info with whoever they like. You clicked the agree button or opened the shrink wrap or whatever so you did agree to this.

          And if your user files aren't encrypted, or stored with with a file system which enforces access control, then simply removing the hard drive and plugging it into an external USB housing on another machine will let you read all the files.

      This isn't about Orange tracking you. You have a contract with Orange and part of the price you pay for the service you recieve is that Orange can track you. Quid pro quo.

      This is about other people being able to track you and find out historically where you have been. The article gives the example of someone getting hold of the database from a backup which seems irrelevant to me. Might matter more if I were the sort to play away, if Mrs iShit wants to know where I've been she's welcome to.

      What I'd find more concerning is that this is available to any app on the phone. Pleanty of apps have been found doing questionable background activity, how long before a freebie ad sponsored game starts feeding this back to the mothership?

          Cell phones

          It's obvious that your phone service provider has to know where you are (at least, in the sense of which cell you are communicating through) in order to route calls to you. The ETSI standards define mechanisms for this information to be recorded and made available to law enforcement subject to appropriate legal provisions. If you're concerned about this tracking, it can be circumvented (at least in normal circumstances) by simply turning off your cell connection.

          But this is very different from the phone manufacturer using built-in GPS to record your phone's movements throughout its lifetime (and sharing that information with 'appropriate' third parties). Apparently the right to do so is buried on page 94 of the 20,000 word legal document that you agreed to by breaking the seal on your new phone.

          Lawyers: start your engines!

            This is very different from what it actually does. It tracks your location based upon triangulation of cell towers (think what would happen to the battery if GPS was constantly on), and also keeps a log of Wifi networks your phone has spotted. You could probably also circumvent this by turning off your cell connection and your Wifi.

            I have an iPhone and this concerns me, but at least get it right.

              You beat me to it, It's one thing to have the cell provider track when you're camped-on to the network , but this would normally be just the tower ID.

              This creepy thing triangulates between "n" towers and records WiFi MAC's - a shitload more detailed information than you (are compelled to) agree to by using a mobile phone.

              There are legal agreements in place to cover disclosure of mast ID's - I would presume "reasonable suspicion" is required, or at least the pretence of it. There is no regulation whatsoever of this new datagrab.

      Orange is your gsm operator

      Orange or any GSM operator in a modern country is bound to some insanely serious laws about such location data. In fact, in some countries, people have died because the network operator declined to give location data without proper paperwork.

      Ask anyone at a GSM operator, even they can't access such data without proper paperwork. Yes the people sitting at their data centers. Every access is logged and there must be something to show for each access.

      Apple is not bound to such laws, especially with their evil genius lawyer written EULA.

    A simple cache file...

    Many programmers will be familiar with cache files. This just stores the results of the Cell ID to latitute/longitude that all smartphones with GPS have to use.

    I've confirmed that eg the area around my own home only shows up once since I got my iPhone (6 months ago)! Hardly tracking to the second... Also the resolution (in the raw data) is only down to about cell tower level.

    All this does is saving my phone making constant queries to Apple for this Cell ID mapping, which is how Android does it. At least this way Apple has no way of knowing what I do every day.

    Oh it saves battery to.

    Any privacy loving person will already encrypt their backups, and apps approved by Apple will not have ways of accessing this file in the phone.

      2. . 3

        And also wrong

        If you had read the cited article, it's not the tower location, it's triangulating your actual location down to a few metres and recording it with timestamps with 1 second precision. And it's not a cache file, it's an SQL database which is not getting deleted.

          @ .3

          If you had read his comment, it sounds like he's actually taken the time to investigate the contents of this file from his iPhone and has not found per second data, has noted accuracy "only down to about cell tower level" (i'm guessing he's not in the position to go and work out exactly how accurate), and has not seen his home location more than once in the data (and I'd guess he's being going there most days in the past 6 months). Kind of at odds with the article, I know, but why shout at /downvote him instead of questioning the article?

          Also, it may be that it *is* a cache file, it all depends on how many duplicate entries one can find - if you find lots then it's more akin to a log file (which should be purged regularly), if you find one then it's most likely a cache file (which really should be limited in size and have least used records removed on a regular basis).

          @ PerfectBlue

          Your assumptions seem to indicate that encrypting backups is not that much of an issue.

          1) Most people won't think about encrypting a back-up (a checkbox on the device's "home" page - not exactly hard - but let's run with the assumption)

          2) Only Tech savvy people will encrypt.

          3) Hardly anyone backs up their devices anyway.

          Based on the above, it seems like the issue of encrypting backups won't affect most people and the chances are pretty good that those who *do* back up are the tech savvy ones (we like backups, after all) who will encrypt said backups.

          @.3 (again)

          If you actually see the file and not go by some speculative articles you'll see it is the cell tower locations and timestamps are precise but towers only get recorded once.

          Here's the SQL for the CellLocation table:

          CREATE TABLE CellLocation (MCC INTEGER, MNC INTEGER, LAC INTEGER, CI INTEGER, Timestamp FLOAT, Latitude FLOAT, Longitude FLOAT, HorizontalAccuracy FLOAT, Altitude FLOAT, VerticalAccuracy FLOAT, Speed FLOAT, Course FLOAT, Confidence INTEGER, PRIMARY KEY (MCC, MNC, LAC, CI))

          as you can see MCC, MNC, LAC, CI are primary keys, therefore will only appear once! So this does not track all your movements.

          1. web_bod

            It's all relative

            Sorry to state the bleeding obvious - but you've identified a bunch of keys defined one table - wouldn't that suggest that the data might be linked to information held in other tables?

            Perhaps phone keeps a unique record of the location of each hotspot/tower and also has a table (with one entry per second) referencing them - you know, some kind of a log - so when you use the two together you can generate a detailed mapping of the phones location over time.

            I think we used to call those kinds of things relational databases.

                      Yes he does say that if used properly law enforcement can narrow down timeframes and areas. But he also says " after looking at a freshly wiped iPhone 3G which was running iOS 4.2.1 which didn’t leave a single building, had points from all over the town."

                      So there seems (and I see this too, both in my data and in the original movies posted) a lot more data in there than actual location. It would be really difficult to pinpoint anyone based on this data.

                      From my own experience I can't even pinpoint my own house to where spend at least 8 hours a day.

                      This opens a lot of plausible deniability cases: if someone claimed you were somewhere based on this data you can easily say you were not and it's all down to the phone caching more than it needed. No one could truthly say otherwise.

                      I agree a lot more research has to be done on this, but hopefully not the sensationalistic kind. That's just destructive and doesn't help much.

          Wow, talk about exaggeration, I was expecting a _really_ accurate trail of where I'd been with my phone. It is _not_ that. It was various dot sizes, very roughly where I'd been in the UK, sort of.

          Apparently I'd visited Cardiff (or my phone has, without me). I think I have visited Wales as a young child, certainly pre iPhone days, nearest I've been since then is Bristol (ironically doing some consultancy for cellco there). It had no indication of my various trips to Aberdeen (nothing North of the Border).

          There is a very small dot (accurate fix I'm assuming?) on my house for one day, when I hit play. I'm pretty sure I've spent more time here than that! There is no dot covering my office, and I seem to be spending a lot more time south of the river than I remember.

          The data is very inaccurate, which greatly lessens the security impact (though does not remove it of course). I did see that I'd visited Exeter and Bournemouth with the in-laws last year, but there are probably easier ways to find that out (like my flickr feed?).

          It seems from other articles I've read that yes - it *is* the location of cell towers and WiFI hotspots that is recorded, *not* the location of the device.

          And whether the data is held in an SQL database or not is immaterial to the question of whether it is a cache.

      The idea of encrypting a backup simple wouldn't occur to 90% of smart phone users. Most smart phone owners aren't technical people. Most probably don't back up at all. Syncing their iTunes with their laptop is probably the closest thing that they get to doing a backup.

        Basics of cell triangulation

        For cell triangulation you need to know where the cells are eg: latitute and longitude of the mast.

        However the network only gives you the Cell ID. So there has to be some mapping for this to happen.

        This mapping is exactly what's cached in this file (it's the cell tower approximate location, not your true location like some people claim) Nothing more to this file really.

        You can either cache this information like Apple, or contact the mapping server every time like Android does (not sure about Nokia but it'll have to be similar)

        1. . 3

          Did you bother to read it?

          It does actually triangulate your position. With 3G, the cell base stations already know their own location and broadcast it precisely so devices can do this.

          Android's online location database is for stations which don't report their location, i.e. GSM (and WiFi thanks to streetview).

                Why are you making me do your homework? That is only a location spec describing how the network can locate phones.

                It doesn't include actually telling the location back to the handset, or even the cell tower locations. That's an optional subscription service from the mobile operator, or given to authorities for emergency or lawful interception.

                It doesn't come standard with your service.

                Because of this Apple, Google and others have come up with databases that locates cell towers from their ID and do the triangulation on their own.

          You are completely missing the point, and probably intentionally.

            Have you read any of my posts? If so you'd this has been covered already.

            Apple and all other smartphone companies need to map Cell IDs to latitute/longitude of towers so that they can make GPS location fix in useful time (ie under 10 minutes). People use that for locations apps, to geolocate photos, etc and would be extremely bored if they had to wait for the GPS chip alone.

            Don't give me the shill crap, I'm a researcher just as the two guys who published the original article on this. I actually look into what am I'm saying, unlike you.

              @ the lot of you...

              Fascinating threads..

              @+++ath0, you have some of this right;

              - The data collected is not terribly precise, and fairly incomplete, leaving it of limited interest to bad/good guys who obtain it (but it might be enough to tie, say, a serial killer to specific locations or movement patterns, or an injunction buster to his MP, or a consumer to certain supermarkets etc..)

              - Apples motivations for this appear to be a mix of the commercial and the practical; improving the user experience, reducing costs to users and apple.

              - This is not a fully fledged location tracker; far from it! If it had really been developed to track you for sinister motives it would be much more sophisticated, Apples engineers are not dumb.

              However, you look like a fanboi/shill because you don't seem to acknowledge that:

              The very act of recording of this data and storing it in plain sight on your handset and it's backup devices is an obvious security/privacy mistake. Apple could have made much more effort to protect it from casual browsing, they could have worked out that this was going to come and bite them later..

              Oh; and they they could have informed their customers what was happening.. but that goes with the rest of Apple's customer handling ethos: "consume! but never question because we always know what is best for you!"

    What I am concerned about is that a cop or a fed with a generic search warrant could snare your cell phone and use the data on it to go on a fishing expedition. If they know where you are, and at what time, they could potentially try to tie you to who knows what.

    Even if you didn't happen to be near an actual crime they could imply that you were and use that to try to entrap you.

That this would somehow work and you'd just go "All right guv'nor, it's a fair cop"? That this would somehow stand up in a court of law? "Well you see, your honour, the subject was clearly in the approximate location at just about the right time.

    the thing that is annoying me the most.....

    If this had been an Android phone - this would now be hitting the national news - "Google secretly stores tracking data on mobile phone users" but as it is - it is Apple - and people are coming up with all sorts of stupid excuses as to why this is a "non-issue".

    A cache file? several people have reported that they have location data turned off and have never used location aware apps - yet the phone has still logged thousands of data points.

    MobileMe? the Apple find my phone service does not have any need to know where you were last week - therefore the phone does not need to keep this information for this service.

    There is NO legitimate use in recording your entire location history - no app needs more than a few hours worth of history (except Google Latitude, but that is stored on Google Servers).

    I have even heard such stupid excuses as "all GPS devices record where they have been" no, they don't.

    "It's for assisted GPS" - no it is not - if I stand outside my house using GPS at 3pm, the satellites my phone can "see" are NOT the same satellites it can "see" at 7pm. From howstuffworks: "Each of these 3,000- to 4,000-pound solar-powered satellites circles the globe at about 12,000 miles (19,300 km), making two complete rotations every day." Besides which - aGPS does not need to know where I was last week.

    But obviously as can be seen on any news site across the web reporting on this story - the "cult" of Apple is strong with people claiming it is a good thing.

    To the person above who believes it doesn't matter as your mobile operator already knows this information - yes - and in order for anyone else to get access to that information - they need to provide the mobile operator with a court order - I don't suppose you have stopped to think that there must be a reason the court has to approve the handing over this data? Something like - it's very sensitive, personally identifiable data?

    1. Anonymous Coward
      Anonymous Coward

      Well yes it is.

      It is for assisted GPS.

      Like you say the satellites will be different but have you heard about this concept called geometry?

      Once you know your location (from the Cell ID) It's actually possible to calculate which satellites will be in view at any given time of day. There's even apps that use that to show you the stars (and satellites)

      1. Anonymous Coward
        Anonymous Coward

        Re: Well yes it is.

        3G masts broadcast their location in their data, there is no need to cache it.

        Knowing which satellites are in view is no use too. The satellites tell you who they are! If you can hear them, you know which ones are broadcasting to you!

        The whole A-GPS argument seems a bit thin to me. Modern chipsets get a location lock within a few seconds. Dedicated Sat-Navs have no access to the cellular network, and they work out where they are pretty quickly.

        1. Danny 14


          but thats because of different GPS chipsets. phones generally use weaker crapper AGPS necessary solutions. Proper satnavs (and bluetooth GPS boxes) have proper GPS chipsets in them - they can pick up weak signals and work out locations faster, AGPS needs to know where the good strong ones are before it goes filtering the time messages.

        2. Anonymous Coward
          Anonymous Coward

          @AC 05:19

          No they don't 3G masts don't send location in their data, unless you subscribe to an bloody expensive location service.

          I suggest you read up on how GPS works for your second point.

          Have you tried using a dedicated satnav besides a tall building? It will takes ages to get a lock. They work because the cars are on the road with open skies all around. I know this well since I have a Sirf III device (one of the most sensite) on by bike.

          AGPS works in these the more difficult, but pretty common for mobile devices, situations.

        3. John Smith 19 Gold badge


          "Knowing which satellites are in view is no use too. The satellites tell you who they are! If you can hear them, you know which ones are broadcasting to you!"

          GPS sat transmit their *own* orbital parameters, along with that of the whole constellation at 50 bits per second. The datastream takes about 12.5 minutes to repeat. Initial lock could take less than 6 seconds using certain methods.

          "The whole A-GPS argument seems a bit thin to me. "

          Agreed. If 3G masts *only* put out a mast ID # (or whatever it's called) *rather* than actual lat/long co-ordinates you might want a database to map them into a location. It would *slow* growing and not need any time data at all.

          1. Anonymous Coward
            Anonymous Coward

            @John Smith

            I agree with you, on the database being slow growing. Unfortunately even slow means data has to be expired at some point, hence the time data.

            Even something more detached from time like a FIFO queue would still denote some time sequence information.

            The developers at Apple would really need to do a complex randomisation of the cache to avoid these sort of issues. By then maybe it would be more efficient just to contact Apple's servers and not cache anything. Oddly enough if they had done that no one would be complaining now...

        4. Owen Carter

          It is agps...

          "The whole A-GPS argument seems a bit thin to me"

          Well get off your ass and do an experiment. Find someone with a modern AGPS enabled phone where the 'location server' can be configured. Nokia Symbian phones have a whole menu where you can turn on/off individual parts of their location service.

          Disable AGPS, reboot phone, see how long it takes to get a lock. Re-enable, reboot, repeat. Do that a few times, especially in complex environments and you will see just how much faster AGPS makes things.

          My N97 mini (approx 1.5 year old phone) would generally take a minute or so to get a GPS lock when I had this off (to save datacharges). Once I got a better dataplan it started getting a lock in seconds. The difference was dramatic.

  20. soaklord

    The title is silly, and must contain useless information.

    Haven't tried this yet, but couldn't you just SSH into the phone, delete the offending files on a (somewhat) regular basis and be done with it? In fact, I'll bet some aspiring cydia developer will have an app for deleting the data soonish. To the poster suggesting google cares more about privacy, you sir have one fantastic sense of humor.

    A couple of different view points

    I have a couple of slightly different view points:

    1) Apple must surely know that people might not want their location at all times to be logged. Sure, there may be a benefit (better battery life, smaller mobile data bill or whatever) for users with the phone doing this. But from a PR point of view surely it would be better to tell the users what's going on under the hood, maybe having an option to stop it, etc.

    2) With Apple having servers that dish up the information on request in the first place there is an interesting consequence for the network operators. The networks are traditionally shy about the exact locations of all their cell stations. A network armed with the locations of a rival's cell stations can work out all sorts of things about their rival's network capacity, operating overhead, etc. etc. That counts as priceless commercial information allowing them to accurately undercut the rival..

    So what's to stop Vodafone (for example) buying O2 iPhones and using them to get a complete map of O2's cell network and thereby deriving performance information for O2's entire cell network? Or have the network operators accepted that their competitors know everything about their networks costs and performances?

    And we do need a popcorn icon.

      Looking at the posts he has made he does indeed come across as fanboi number 1, but on this occasion I think you will find it is with good reason. He is correct, look at the data for yourself, it is not as accurate as the researches are making out. Or certainly not in my case.

      Really smart

      So you really think if Apple would want to hide this they would store a cache file in your own device, as opposed to just using those convenient wireless connections to send it back to their servers and not leave any trace?

      But SONY surely got caught

      and Apple's no different and deserves to be summarily fucked over this!

        Sony music had some real bad luck

        They got busted almost instantly (good for them!) because World's most advanced NT kernel hacker (now at ms) turned out to be fan of poor band that got cd rootkit.

    I don't have a problem with the information being gathered

    as we all know this is a legal requirement on the case of the networks, and I can see why many elements of the iphone app's and services need the information, not least for the ability to use the phone and wifi.

    I can see how legacy information might be useful so it is left on the phone (although more likely that it takes up so little space it doesn't matter).

    For me it's more the matter that it is available on the pc you sych to.

    And also the fact that the app to look at it is Mac only! I want to see where I've been!

      aaarghhh - you cannot be serious!!

      so many faults in your post.

      1) the network stores your tower ID and any calls. it does not triangulate nor does it log WiFi MAC addresses.

      2) running applications might want to use the data, maybe to suggest the nearest polo-neck experience. They do not need storage for the last x years.

      3) the phone does not need any of this stuff to "work"- it needs to talk to the mast but has no need to log the ID nor even store it temporarily, outside of the 3G stack itself.

      4) similarly the WiFi MAC address, yes it is needed to connect, yes it needs to be stored if there is a password to remember, but not if no connection is attempted.

      5) "so little space it does not matter" - that is SO not an argument. Murderers kill so few people...

    "Legitimate"* reasons to record this information

    1) Apple want to know where you are so they (or their "partners") can supply targeted advertising.

    2) Bloat up the memory so you need to replace/upgrade faster than if this "feature" were disabled (can it *be* disabled?). A time honoured MS tactic.

    3)Enable the offering of a "people tracking" service to "authorised" customers that offers them useful information from day 1 rather than waiting for the suspect (because clearly you are doing *something* suspicious by someones yardstick) to do something interesting.

    I was originally going to ask "why?" but there are plenty of reasons why. It's just that, had I bought one of these things, *none* of them are reasons that help *me*.

    *As in legitimate ways to get more money out of our customers that is.

    And also this report from Michigan

    It seems that none of these phones are secure.

    See this URL, and note that the situation dates back to 2008.

    The device that is being used is claimed, by the manufacturer, to be able to access all the data on your phone, bypassing the password protection.

  47. Ilgaz

    Nobody can fix it

    The owner community of the device already started to apologize for Apple. The owners themselves.

    So, really don't even bother to comment about it. It is like trying to argue with some cult. Pointless...

I don't see any specific locations, my house isn't even on there, just a bunch of pins showing masts in the area.

        As Apple desktop user myself

        It became really hard to defend Apple because of their rude, sometimes swearing cult like fanatics. Apple is being driven to very bad decisions because they are listening to their noise. Some flaw like this, happened to any company except Apple could drive the CEO or very high level staff "retire" because they have healthy people who critize their bad actions.

    * Pandora radio transmitting real location of users

    * Online tracking such as the Facebook like button or that done by ad networks (remember the recent "do no track" option in some browsers?)


    people choose to pick on a harmless little file that only caches the cell phone masts the phone has seen, used for the phone's own location services to work.

    The police can get a lot more than what's in that file just by calling up the mobile company.

    Don't want to risk other people finding out which cell towers you may have hanged around? Just check "encrypt backup" in iTunes. There's a lot more valuable information in your phone than this if it fell into the wrong hands.

I don't see any specific locations, my house isn't even on there, just a bunch of pins showing masts in the area."

    Err, that package has been neutered so there will be less detail..

    "The researchers have released open-source software that makes the entire process a snap. It also plots the information to a map that shows the movements of the user. While the locations are stored down to the second, the researchers said, their software intentionally reduces the time to weekly increments to make the data less useful to snoops."

    Has anyone here given it a full analysis that stands up.

    1. JonHendry

      But it's still just the masts

      Even if it's down to the second, it's still just the cell tower locations, which doesn't give much resolution. It's not going to be enough for someone to be able to tell you left the office, walked down the street a block or two, and popped into a hotel to meet your mistress or into a massage parlor for a happy ending or to meet your dealer to score some smack.

    Not going to read all of these comments...

    ...but this is not news by any means and there is an en excellent analysis and explanation of how and when this was first 'found' here:

    Me, I'm not really bothered that someone *might* be able to get hold of my phone and then see where I've been: Should it be used for location-based advertising I'll simply opt out (since I'm pretty sure there would have to be an opt out clause somewhere). I suspect people are getting their pants in a twist about nothing much really.

    1. LyingMan


      .. The point is that the data collection itself is not opted in.. The right way for the collection is to be opted in.. not default as 'opt in'..

  58. Pet Peeve


    I ran the program. The database is not where you've been, but what cell tower and wifi networks you've been in range of. I was on a trip to San Jose last month, and there were points on the database that were 75 miles away from there. It's not a breadcrumb of your exact gps track, it's the resources that the phone used to connect, or to provide you with GPS info during the trip.

    It's definitely a good idea to encrypt this better, but not for the reason you think - it's an EXCELLENT resource for determining exactly where cell towers are - it makes a little circle for each one. That's not really information that you want so easily collected - I think it's quite possible I could drive around a city and collect the location of every piece of cell radio infrastructure in one day.

  59. JonHendry

    Eh. Low resolution

    I checked my recorded locations stored during a recent weekend in Philadelphia.

    The resolution is in terms of blocks. You can tell I was in Center City Philadelphia, and popped over the river to the University of Pennsylvania campus. But the towers recorded are farther south than I actually went, and one is farther west. (I stopped at 33rd street, but apparently my phone pinged a tower at 38th street.)

    There's no adequate motive to explain what Apple has gone to this trouble to do unless they're making money. Perhaps they are collaborating with social network sites who would love to get their hands on this data and could easily use their iphone or computer app to retrieve it.

    1. Ilgaz

      Don't go that far

      Apple can't gamble that much and Facebook and Twitter are already being pressured by Govt. for more sane privacy settings.

      A California company doing such a nasty privacy crime would go out of business, especially California. Notice some sites have "your californian privacy rights"? It comes from the amazingly strict law of California.

  61. TheOtherHobbbes

    Oh the drama

    Having just downloaded the application and looked at the data, here's what I found:

    1. Location accuracy is wretchedly poor, and frequently wrong. Apparently I've been on day trips to Newport, Oxford and Weymouth recently - which is certainly news to me.

    2. The best accuracy is maybe half a mile.

    3. In all the years of tracking data I've collected, I've never been at home. Not once.

    So... the assertion that this is uber-spy Big Brother monitoring is clearly nonsense and wild exaggeration.

    The only conclusions anyone can draw from the collected data is that on [date] you made a journey to [region.]

    If [region] includes a city, there's a good chance you went to that city - probably.

    There's *no chance at all* of getting anything as accurate as a street address, or even a mode of transport. (Car, bus, or tube? No idea...)

    Now - this doesn't mean Apple should be collecting this data.

    But that's for two reasons.

    One is that it's not Apple's business.

    The other is that this data is so useless it's difficult to see that it has any value to anyone. It's useless to advertisers, useless to Apple, useless to law enforcement, and useless to the emergcency services.

    So the real issue is - why bother at all?

    Were these just bundled in to make the thing more comprehensive? Let's say I have a wifi-only iPad (as in fact I do). When this has no connection, I really doubt anything is tracking it. A couple of apps have asked if they can use location and been told no.

    So perhaps it depends on which iPad you have. I'm more worried about my car's GPS. I'm SURE that thing is tracking my movements.

      Everything should be judged coming from a presumption of innocence. This presence of this file is very easy to explain if you understand anything about software and how GPS location works on phones.

      If it wasn't believe me I'd be among the first up Apple's throat.

        I gotta question for ya, shill ...

        An internet (browser) cache stores info on a computer under the assumption that the individual user, who owns the computer, will frequent specific internet sites, thus minimizing transfer of data and minimizing bandwidth use for that individual.

        Said stored ("cached") data is only stored when requested by that user, and only used when re-requested by that user.

        On the otherhand, when I am using my telephone, I expect it to find the nearest ("least costly") cell tower, and make the call accordingly. Why the hell should my telephone need to look thru' a database that includes my time/location information, detailing when I'm in Forresta, Graeagle, Fort Bragg, Covolo and Solvang, when I'm in Grass Valley (all in California)?

        The answer is that it doesn't need to look thru' that database. All it needs to do is get the signal, and act accordingly. In fact, that database has absolutely zero use in the day-to-day life of the consumer.

        Yes, the telcos are probably required to keep "who was where, and when" info ... but on the personal hardware of their customers? Not so much ...

        IMO, that database only exists to track the user, for reasons that are uncertain. And that is an extremely good reason to avoid AAPL products at the consumer level. It is a personal privacy invasion atrocity looking to happen.
