Throwing this out there to see if anyone else has had this experience or ideas on how this is happening.
Dairy Queen -- I told a story here about Dairy Queen being out of ice cream. Google toolbar is installed in browser. I was immediately served with DQ ads.
Toothpaste -- I had a cleaning appointment today, very nice young (pretty) hygienist was giving me advice and recommended a specific kind of toothpaste. I had only my phone with me and used Notes to note the name (although I had misspelled it as is my custom [GMan!!!!]). Went to Kings on the way home and bought it. Come home and am served ads for it.
How is this happening?!?
Best I can figure is Google is sending this info via browsers/toolbars. But I can't explain the toothpaste. Did my iPhone X spy on that convo? It would have had to use the microphone and be able to interpret the brand name (not common).
