Below is a disturbing amount of information data brokers have ammased from buying your data from trackers in ads and apps.
“a staggering amount of sensitive and identifying information about consumers,” alleging that Kochava’s database includes products seemingly capable of identifying nearly every person in the United States.
… can access this data to trace individuals’ movements—including to sensitive locations like hospitals, temporary shelters, and places of worship, with a promised accuracy within “a few meters”—over a day, a week, a month, or a year. Kochava’s products can also provide a “360-degree perspective” on individuals, unveiling personally identifying information like their names, home addresses, phone numbers, as well as sensitive information like their race, gender, ethnicity, annual income, political affiliations, or religion, the FTC alleged.
… target customers by categories that are “often based on specific sensitive and personal characteristics or attributes identified from its massive collection of data about individual consumers.” These “audience segments” allegedly allow advertisers to conduct invasive targeting by grouping people not just by common data points like age or gender, but by “places they have visited,” political associations, or even their current circumstances, like whether they’re expectant parents. Or advertisers can allegedly combine data points to target highly specific audience segments like “all the pregnant Muslim women in Kochava’s database,” the FTC alleged, or “parents with different ages of children.”
Get GrapheneOS, your mobile phone will be one of the best sources of data about you, and if you’re on Googled Android or IOS, there’s nothing you can do to stop google apps stalking you, which they have already had several lawsuits about doing it even when you disable it. GrapheneOS takes care of it by sandboxing google apps, so they can’t do almost anything, along with really fine-grained permissiion control, i.e giving messenger access to only selected photo you want to upload, and nothing more.
As far as browser goes, I recommend Mullvad, and bundle it with their VPN. Not only can it be payed for by Crypto, it also means that almost every other VPN user will have the same browser fingerprint as you - fingerprint of the Mullvad browser, which is based on Tor browser and designed to be as unfingerprintable as possible, so it will be really hard to distinguish you using secondary fingerpriting, such as extensions or minor browser details.
Don’t use Gmail or GDrive, ideally get your own NAS for file sharing and switch to something like Protonmail, which now also offers Drive. Get a domain that is vaguely company-sounding. Something like @techcorplimited.com, and create a catch-all email address, so any email sent to that domain will end up in your inbox. You can now use [email protected] as your throwaway email address, and just randomly generate them for all services you use, while also making it believable to confuse even AIs.
Even when using VPN, don’t sign into your accounts. You don’t need to sign in to Youtube to tell it that it was you all the time, just remember your favorite youtubers and look for them by hand every time.
