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.
Yes, you give location access, but you may disable storing location history. It does not show me what I searched or where I have been. I temporarily turn it on during a trips, otherwise I do not need it.
