back to article Android data slurping measured and monitored

Google's passive collection of personal data from Android and iOS has been monitored and measured in a significant academic study. The report confirms that Google is no respecter of the Chrome browser's "incognito mode" aka "porn mode", collecting Chrome data to add to your personal profile, as we pointed out earlier this year …

    "The nature of some data may also surprise. App developers receive your age and gender whenever an app is launched, the study found."

    And the accuracy of that age value is not high (I assume age would be from someone having a google account .. but nobody with any sense should use their real DOB when registering with gmail, fb, twitter etc. as DOB is one of the key identity theft targets*)

    I assume "gender" found in same way? (presumably with lots of different options these days for covering gender fluidity)

    ..* and yes, that means you (& friends & relatives) not plastering birthday photos across social media - no point hiding DOB if there's photos of you celebrating 21st birthday (or whatever that also gives year as well as day / month)

    Being "camera shy" is handy in these days of social media overshare

        'gender' refers to the masculinity or femininity (or lack thereof) of nouns and other parts of speech, in languages that have such things (like Spanish, French, etc.).

        For human chromosomal arrangements and the associated secondary characteristics, see 'sex'.

        (any other usage of 'gender' to mean 'sex' simply smacks of political correctness and deserves ridicule and contempt)

          It's the combined field values "cnt=1" and "cust_gender=2" in the snapshot.

          The 4 combinations give birth gender and current gender, set by primary sexual characteristic currently fitted. Fails to cover neuters and those rare occurrences with both kit.

      Fake DOB?

      I used to put in bogus DOB etc...and then I lost access to an old email account, which then meant I couldn't recover my ebay password, which means I lost 5 years of eBay seller history... etc etc.

      You can't put in fake information that later might be used for account recovery unless you are planning to then write that all down somewhere. At some point you'd have to memorize an entire fake identity or two or three... sure some people do this but come one who has time?

        Whether or not it collects PII depends on how you define PII. It collects far more information than I'm willing to share, which is why I always block GA. If your data collection needs are limited to load time stats and "journey", then why not do this with your own scripts? Just keep it between you and your users.

It's been mentioned here many times. It's why the OP gave those recommendations and why we don't trust Google.

              Sadly my antiquated Nokia N95 died a year or two back.

              A trip to cash converters and £40 poorer, a slightly less antiquated blackberry replaced it. Yes, it doesn't do all the slick things android and iphone do, but I feel like I have some control over using it.

              Sadly though, as I also found out 15 years earlier, BB's are a pile of tosh compared to Nokia.

              Bonus? The battery last a week, the phone can be easily dialed in the dark and the rain, it's not as hard to hold as a "slate", and I don't have to worry about things slowing down because youtube decides to launch in the background.

              Yep, I'll keep my android hacking to the comfort of my armchair.

              Whilst I'm ranting about the horrible shape of all mobiles these days, I wonder, what happened to HCI? Why has user interface gone from practical to fashionable?

              A few months ago, I splashed out a few hundred on a high specced android tablet... it's so thin that after a while it digs into your hands a bit, and the edgeless screen means my fingers keep drifting into pressing something I don't want to press... For non-intensive use, I literally use my old £40 tablet more often, because, well, borders, and more rounded sides.

      Re: 'The nature of some data may also surprise. App developers receive your age and gender'

      I was with you until the second word of the second paragraph. "Leverage" is not a bleedin' verb.

      The truth is that Android is a system to turn a smartphone owner into a product. The only way to successfully avoid that is to strip out Google services framework completely which, in essence, means running a custom build of AOSP/LineageOS/AOKP/Omni without the final flash of gapps. Then add F-Droid, YALP¹ et al.

      Even then, you have to be bloody careful. aGPS will quite happily talk to Google's SUPL server and quite literally hand them your coarse location along with device specific information. If you have a Mediatek device², their proprietary GPS core will also talk to their server. All of this is before the networks get involved.

      As for Android being open source, the first time you build your own derivative you'll realise just how much of it isn't. Even Qualcomm based devices, the vendor most likely to play nicely with your *droid freedom project, is chock-full of binary blobs from the obvious RIL/modem (pretty much expected as raw access to this can be used for all manner of nefarious things) down to simple peripheral access.

      It's a shame the Replicant project was such an epic fail but that was to be expected. The smartphone environment deliberately doesn't support full freedom as most devices are simply loss-leaders which enable access to the real product: You.

      ¹ Take no notice of apps that declare they're GSF dependent. Parts of them may be, yet they're usually deep down betrayal bits that don't affect core functionality. Of course, if you're installing even one closed-source app from GP through YALP, all your hard work deGoogling your device has gone out of the window anyway.

      ² Avoid at all costs. They almost always turn out to be landfill devices.

        Correction : The only way to successfully avoid that is not to have bought a phone with Googles Android on it in the first place.

          Correction : The only way to successfully avoid that is not to have bought a phone with Googles Android on it in the first place.

          In an ideal world, yes. However, you try getting something with the screen, processing power, ancillaries and connectivity of an Android device without the Trojan horse OS for reasonable money. Far better to take advantage of their "kindness" and gut it of its traitorware.

          This isn't blind trust. I run multiple utilities on the device itself via root adb shell to ensure I haven't missed anything any time there's a major change. I even strip out bits of Lineage that I don't trust such as the Jelly browser, e-mail, messaging and their update and feedback apps. In their place is Firefox Mobile, K9Mail, Silence and sod all because I'll track changelogs myself. Gone is anything Googly-syncable and in its place is DAVDroid and a self-hosted Nextcloud backend.

          Not for everyone, I admit, yet for those of us for whom messing with builds is more fun than chore, it works. We're not going to change the world for Joe Public this way, though.

          Andoid devices have been a Trojan for Google to get inside your walls almost since they first came out.

          Agreed. My first 'droid device was an Orange SanFran simply because that was the first reasonably priced handset that was a doddle to unlock, CMify and disinfect right out of the box. Its stock OS lasted just long enough to remove the SIMlock.

        I'm messing around with one now.

        It wasn't just the apps that have been modified, the whole system seems to be corrupt.

        For starters, there are system apps which install apps without user intervention.

        What's even worse is that even the developer options have been crippled or modified.

        Enabling the "show CPU usage" in Developer options didn't show anything on-screen at first until turning it off and back on again but even then only one or two processes show on-screen.

        Looking at logs shows dozens of errors of: "ProcessCpuTracker: Skipping unknown process pid ****"

        that accounts for this oddity.

        Bugreport is completely greyed out in Developer options.

    no shit - comparing Apples to Oranges. An Android connects to Google for "Androidy" things, and for Ads (in apps / webpages, etc). An Apple connects to Apple for "Apply" things, and Google for Ads (in apps / webpages, etc). So therefore the Android connects to Google more than the iOS thingie connects to Apple.

          The point of a company is to provide a good or service in exchange for a reasonable profit. There's nothing about a company's goals that requires the company to treat its customers like walking wallets. A good business of any sort is one where both the business and their customers profit by the exchange.

    Android is Google's monetised trojan horse and the only reason they got away with it for so long: It was the wild west as far as Mobile platforms were concerned. This level of data slurping would not have been tolerated on a mature sector such as PCs, where users became savvy over time. Sadly, Microsoft's Windows 10 has gone the same way. NEVER 10!!!!!!!
