Your phone told advertisers you were located at Lowe's using GPS. Then your credit card company told advertisers you bought drill bits. If you looked up any cabinet door handles in the past, that data was given to advertisers too. They put all those pieces together to serve you more ads on drill bits and cabinet door handles.

A lot of stores keep track of which aisles you spend more time in, that information is then shared with their "partners" (ad networks). By the time you made it home, they had already shared that you bought bits and that your device spent a while looking at cabinet hardware.

I'm sure there's more than a little Baader-Meinhof happening. I did expand my privacy a bit; pihole, searxng, some other stuff and I notice it less now. Or I think I do, humans are notoriously bad at this.

I've been advertised things that my wife has talked to me about that i otherwise have no interest in. I absolutely believe my phone is listening.

Sure. If you actively turn it on, and all involved know it's on. But this is always active as far as I'm aware.

I'm guessing it'll be toggle off, and it'll toggle itself back on every update.

In other words, they're taking your data for their use all the time, and sometimes they'll share your data with you.
