I heard android phones are secretly reporting to google all the time what you are doing, if you are walking, seating, riding a bicycle, running, or standing...
Last week, I was talking about buying a trimmer with my wife. It wasn't over phone. It was my surprise to see ads for trimmers everywhere. I don't think it's a coincidence. We are being tracked all the time. It's hard to avoid all these. Also, it's not me. I have seen this a few times on quora/Reddit, asked by some other people.
Too much offtopic here. Sorry mods
