Seems like most of my data they got from apps on my Android phone, there was even an app that I just installed, opened and uninstalled in less then a minute without even logging in or anything.

How can I block them in the future?

set the "limit ad tracking" feature on your phone at the os level and the advertising id will become unavailable to everything. On Android this is Settings > Privacy > Advanced > Opt out
