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.
That’s why you use hide-my-email aliases when you sign up to sites, so they can’t tie “your” email to you anymore.
Create a few junk accounts, send recovery to a hide-my-email alias
If you use password managers it really is no bother to have multiple accounts, and Proton Pass integrates hide-my-email, it’s pretty neat.
Thanks for the hint with hide-my-email! I will ask my mail provider, if they offer something like this as a service.
