I think hexbear has them. Is it a connection thing where cookies spot other cookies? Do tracking cookies matter when it comes to insurance and therapy sites/apps? I'm thinking about therapy that I saw advertised on YouTube, and I bet they're somehow sketchy. And their app requires the use of third party tracking and cookies.
I just don't want these sites/apps to see I'm a communist.
the deal with third party cookies, is that you go to example.com, and example.com loads in code, or assets like images, from another site: say, a facebook like button. Up until the last few years, since that secondary request was going to facebook.com not example.com, it would be able to set/view cookies on your browser that belonged to facebook.com, not example.com.
That allowed them to identify your browser individually (and tie to your user account if you had one) across all sites on the web that embedded a facebook like button, building a profile of what sorts of sites you go to. But it couldn't detect your entire browsing history, just when you went to sites with embedded bits from facebook. Hexbear doesn't embed that stuff
Thanks
