Slightly unrelated but something amazing and terrifying happened two days ago. I moved about 6 months ago and I keep a separate OS (Windows) for mainly gaming.

When I was waiting for some updates to finish, I was browsing HN and came across a Show HN that shows you food places etc (https://www.justgetmefood.com/ - https://news.ycombinator.com/item?id=17746497). Since I was on my gaming OS, I was not logged in to Google or any of my accounts, only Steam and some other non-important things.

I tried out the app, and it promptly showed me restaurants that were 20 minutes of walking distance, from my old place! Down to the street-number. Even though I never gave away the address on that operating system (also installed after the move actually). Somewhere along the pipes, Google picked up that this was me (IP probably?) but somehow mapped me to the old address.
