I’m trying to understand how an app would even get that info in the first place, how that’s classified and why a mobile operating system even has a way to provide that data.

Am I correct in assuming that if an app is used without play store / play store framework that it would not be able to get access to that data?

Thanks!

    All due respect to my fellow lemmings, but the ones in these comments are vastly over complicating this. It’s extremely simple - you give that info away, and you do it happily. Here’s an extremely simple example of every single one of your questions:

    Financial

    • you explore job postings on linked in. You upload your resume to Google drive. You say where you work/what you do on your social media. Your bank statements get emailed. You check your credit through an email reminder.

    political

    You subscribe to websites with particular political leanings. The content you engage with on social media falls in certain political camps. You interact primarily with people that also have those leanings. You block or avoid content that is not to your politcal liking. Every like and subscribe is your personality and political affiliation.

    health

    You searched “symptoms of (insert thing here).” You ordered a next brace on Amazon. Your doctor sends your invoice to your Gmail account. Cvs emails you your receipts.

    religion

    See politics.

    browsing info

    Google literally sells everything you do. It’s their business model. Every time you’re signed in with Google it’s tracking what you do. Every email you receive. Everything you click on. Every item you purchase. Every review you fill out. Google sells it all, and you’d be amazed how fast they do it. Fun experiment, go buy something - jeans, a shirt, shoes, drums, and guitar, whatever from a new place you haven’t shopped before. Go buy it and have the invoice go to your Gmail account. Then get on Instagram…time how long or far you scroll before you see an ad for a similar product. Perhaps even a brand you comparison shopped.

    You tell it all these things. Whether you realize you’re doing it or not, you tell it everything it wants to know just by using your phone. Google sells it, instametathreads buys it, learns more, and then sells what it learns back to Google and advertisers. Rinse, repeat.

      Clarification, Google doesn’t sell the info itself, it guards that jealously, they sell targeted advertising. They say “we can make sure your advert gets to the people who want your stuff” to the ad companies and sell advertising space on that premise. The ad companies don’t know your political leanings, but Google does and makes its money by targeting you with ads relevant to that and other aspects they’ve identified about you.

      Google/Meta don’t sell the info specifically because that info is how they provide their “unique” service.

    From what I know having worked in adtech,

    • they collect as much information as they can from the device such as location from GPS, interests from follows, likes dwell time on posts, and other information you knowingly or unknowingly provide. This includes scraping information from photos and videos you upload to the app. Eg, you upload a picture of an expensive bag with the caption “my new bag” - the bag brand can be determined and assessed algorithmically.
    • the above extends to websites you visit with in-app browsers and the actions you take while on those pages
    • deduce what they can’t eg where you live & work based where you spend time during the day vs night,your real life interests based on places you visit eg gym, fast food places, church etc. Also they apply complex algorithms to relatively accurately deduce anything you don’t directly provide. Eg if you disable accurate location, they can figure it out based on the ip address(es) you connect to the app from (geolocation algorithms) .
    • and what they can’t deduce is bought from third parties. Those are companies normal people don’t know exist whose sole purpose is scraping and categorising information - sort of similar to credit agencies but different. In this case, they take what they know about you and send it to this third party which then returns eveything they have that’s related. Eg the app (threads) might send your email and username and get a response containing your previous home address (say scraped from some insecure government website)

    With the above, even without knowing your name (this can easily be determined) , they are able to know enough about you to determine the kind of person you are, with whom you interact, where you go, your political affiliations, job, salary estimate etc and sell it to advertisers. This is usually sold as “audiences” but given the tools provided to advertisers, it’s easy to create hyper targeted ads and recommendations (remember Cambridge Analytica).

    We voluntarily give up a lot more information than we realise.

    And remember, the smartest people on the planet work at these companies, so the above is nothing in comparison to what behemoths like Facebook, Google, Tencent, etc are capable of.
