I have the location in my Android inactive and everytime I open google maps I get the message:
"To continue, let your device turn on location, which uses Google's location service. cancel - ok"
I have to click cancel every time. I think the language is disingenuous, because if you click cancel you can use the maps anyway. I suppose I should stop using Google Maps.
I use duckduckgo in my android, and the other day I realized that the keyboard where I'm typing is "Gboard - The Google Keyboard".
I suppose it's not calling home with every key, but who knows?, or, if it's not calling, if this will change in the future.
