" oh sweet summer child " you might be thinking, and yeah. I got no clue.

A thing I appreciate about Lemmy is the tech savy, privacy conscious crowd. Since joining I’ve seen these topics discussed a lot more often so here I am, wondering how much and when do apps collect information about their users. Most people usually don’t mind or don’t notice this, and those who do often come across as conspiracy theorists.

What I’m trying to figure is what exactly gets mined, how, and for how long. I heard some apps track your eye movements or record your camera at all times. I’ve heard that Google records your audio 24/7. I find it hard to believe this would happen all the time as it sounds like pretty expensive process in phone resources as well as space (information is unlikely to be stored on video format, right? Is it even human readable at all?) Obviously if I purchase something online or if I’m browsing for a specific topic on any app, that data is gathered and used- I’ve seen it myself, after browsing about X, or purchasing X, I’ll see more ads and content similar to X ( if it makes it past my adblocker of course, but it’s hard to block ads on some apps). Now, does Google truly know how many times a day I fart ? Does Instagram keep track record of people’s faces and underwear color when they scroll in the toilet? Does it happen in the background at all times or only while I use those apps?

These are the stupid questions I need to know about. Sources appreciated. TIA.
