Whatever data is collected seems to be aggregated in digital storage facilities.
Unless it was only part of a psyop, some of these got leaked to me via Waze one time when I input my address without GPS on. The app seemed to pull up locations where my address was being stored in large data storage facilities. I google’d them and looked on maps. Some were data centers, and others looked like front orgs with data centers behind them.
