I'm OK with data harvesting, but, it has to be transparent and ask for permissions every time they want to use my data, allow me to delete the data I generated. It should always be opt-in.

I use google maps a lot. I search a place, it provides me lots of useful information. Yes, I find it helpful, but also terrifying, especially with the "Popular times" section, which is "based on visits to this place."

Where are the eyes? :/
