(assuming you are on Android) Google's algorithm knows you opened your browser. They almost certainly know what page you opened and how long you have been on it [on chromium, everything typed in URL bar is sent to them]. They probably know that you asked the above question. If it is a cheap android phone (or even if not, if it uses Rockchip chips, if it is a Xiaomi and likely if it is a Oppo) then at least one Chinese corporation, with ties to a very sophisticated gov apparatus knows it as well. Considering how many permissions they allow each app to receive (esp. on older versions, which are the majority of users) other apps likely know it as well. I have a Samsung, and there are lots of clues that they know everything I type and a lot of what I say as well. Probably other actors as well, since a porous pail will leak...
