It probably uses bluetooth to triangulate your phone to other phones and other known stationary devices for exact position, with time spent, where. Big stores do it but they don't tell you. And expect all to have facial recognition cameras. Do you have happy face? Frustrated face.
Maybe the hardware store sends their purchase info over the net to home base. Aggregate data over time. People in this location bought that. Or they took photos of the hardware isle which were geolocated. Paired with your data, the system knew you were not sure because of time spent in the bolt isle.
And your phone is used as a relay for other program pings such as 'find my phone' 'tinder' 'vocal commands' remote camera activation etc.
And that is why a giant smartphone battery lasts half a day without use..

You need your tin foil hat for that level of paranoia. They can't just log into your Bluetooth unless you agree. And Stores are not going to share purchase data unless someone is paying them large bucks. Find my phone is only good for people you share with.
