How did you block all that? Can duckduckgo block apps from accessing that data? There's no website version of threads yet right?
Edit: nvm. Duckduckgo has an app tracking blocker built in these days. Coolcoolcool
This is what I got after 5 minutes.
I understand getting location because the big companies have country specific websites that have different pricing and products but why boot time?
If they collect enough metrics and link it to a single user they can use that as an id to tell if that user does things outside of their app. So they collect all the data and build a device finger print then they offer tools to website developers for marketing (Facebook tracking pixel, like buttons, etc ...). Those developer or marketing teams or whoever add it into the other apps you use and Facebook can track you without you being logged in.
my guess is so google can use this data for analytics for their operating system since it collects OS version too
Delete them? Just dont install the damn app, stop using facebook!

That seems so unnecessary. Why do they want to interfere with screen density??
So they can build a better profile of you.
Screen density is usually needed to work out the resolution of images to load. A high-DPI ("Retina") screen uses higher-resolution images than a low-DPI screen.
