> Or is it cheapo Android Phones picking up the tag and then sending GPS coords into cloud?

AirTags have no integration with Android devices. There's a shitty app from Apple you can install that allows you to scan for AirTags nearby, one shot. It's supposedly against stalkers, but it's practically useless. There a bunch of other community apps with varying features like finding and notifying you there's an AirTag nearby. But you can't even track your own AirTags from an Android device, because Apple have decided you must do it from an iDevice. No browser, no Android app. You can check your iPhone's location via the browser, but not the AirTag.

The Android ecosystem has an alternative thing, but depending on the phone manufacturer you have to opt in to your device being used to track trackers around you.

When I travel to places with low iPhone market share, I always have one tracker of each ecosystem, just in case.
