Your Apps Know Where You Were Last Night, and They're Not Keeping It Secret (nytimes.com)

Posted by msmash on from the closer-look dept.

Dozens of companies use smartphone locations to help advertisers and even hedge funds. They say it's anonymous, but the data shows how personal it is. From a report: The millions of dots on the map trace highways, side streets and bike trails -- each one following the path of an anonymous cellphone user. One path tracks someone from a home outside Newark to a nearby Planned Parenthood, remaining there for more than an hour. Another represents a person who travels with the mayor of New York during the day and returns to Long Island at night. [...] An app on the device gathered her location information, which was then sold without her knowledge. It recorded her whereabouts as often as every two seconds, according to a database of more than a million phones in the New York area that was reviewed by The New York Times.

At least 75 companies receive anonymous, precise location data from apps whose users enable location services to get local news and weather or other information, The Times found. Several of those businesses claim to track up to 200 million mobile devices in the United States -- about half those in use last year. The database reviewed by The Times -- a sample of information gathered in 2017 and held by one company -- reveals people's travels in startling detail, accurate to within a few yards and in some cases updated more than 14,000 times a day.

    Most apps are complete shit whose sole purpose is to track you, show you ads, and sell the information about you.

    If I install an app (very rare these days), if it asks for my contacts and my location information, I uninstall it.

    If people would understand how much of their privacy they're giving up to asshole marketers, they'd be uninstalling this shit and realizing that most apps provide nothing that a web page can't give you.

    I have very few apps on my phone, and have pretty much decided that most mobile apps are something I can live without.

    I simply refuse to use location services, because the majority of that isn't going to benefit me, it's going to benefit some asshole ad company.

    Fuck that, fuck apps, and fuck ad companies.

      The fact that Google is one of the most popular brands among consumers,
      and the fact that millions upon millions (perhaps billion(?)) people are on Facebook shows you how little people care to know, and care about privacy!

      Despite all the noise about Facebook freely sharing user data with third-parties,
      and despite all the noise about Google providing a backdoors to three-letter agencies.

      It's a sad state of affairs!

      I think most people don't know about the privacy issues- and many that do feel like they "have to be on facebook to stay relevant" (ridiculous belief, but one shared by many). Honestly, you can say it is the user's fault, and in large part it is (but really, do even relatively informed people know how often data is shared about them and who is sharing data about them?)

      I bet each and everyone of us has had data about us shared WITHOUT us knowing.

      A lot of businesses in the IT sector would hate this, but I would propose making it illegal to sell data on a individual WITHOUT them giving explicit consent EACH TIME. So, just having a EULA saying "we're going to sell your data and you give consent" is not enough. If Facebook want to sell information to Wells Fargo- they have to get your permission first.

      I think we could cut back on 90% of privacy violations with such a ruling.

    I recently visited a retirement home, for a community event which was held there. Nobody knew me there, and I didn't talk to or identify myself to anyone, I just listened. Shortly afterwards, I started seeing ads for the retirement home in my Android phone browser. I can only conclude that Google is sharing my GPS location with advertisers...

    Wait, what? How do you guys not know how this works? Location based advertising has been around for years. How do you possibly not know that one of the biggest ad agencies on the planet (Google) DOESN'T do this?
