That is something that I like about Google. It only takes a minute to get to what they admit to data they have collected. Also easy to dump all data and then download it a few hours later. I mostly just use paid for services (GCP, Play books and movies, sometimes Colab Pro), but Gmail is my backup email and I like to download that occasionally.

re: Amazon: I like to refresh my VPN IP address, and go to Amazon in a private browser tab to avoid being "gamed" on item pricing. I login once I have the price set.
