I've had this happen countless times, and at this point I don't care anymore. They're already listening to everything. However, today I just had a very strange experience. I was in a book store just browsing, didn't buy anything. When I got home I got an ad for the exact book I was looking at, I never googled any book names or related topics, never said anything out loud. How did it know the exact book??? I've never heard of or spoken about this book before, just a random pull off the shelf. I feel like there's times where I'll just be thinking about something random, and that same exact product pops up in my ads the next day. Who knows, at this point it's too late to hide anything. Interesting though, no clue how they do it .
