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.
Legitimate question. Targeted ads feel obvious to many, but it is more about control.
You are absolutely right, I am surprised again and again. But I do my best to avoid it, if I find something that tracks me. And I am surprised that so many people let themselves being exploited, and even defend this exploitation.
Free yourself! It is work. But it is worth it. And it is not too late.
