I am genuinely horrified to see how much data google collected from me
I created a google takeout and in that zip file I found some files containing a ton of data about me. It has logged every single page I visited while using the google search engine and chrome browser. It even logged every single time I opened an app on my old android phone. It even has VOICE RECORDINGS of me and a log of every time I used google assistant. This is just some of the data and I'm very sure there is even more data they have.
It's not even online only anymore. You can't do the setup process of Android OR Windows without connecting to the Internet, and I doubt Apple's products are any better in that regard.
