While FindMy is running, it stores the information of your devices in temporary files ~/Library/Caches/com.apple.findmy.fmipcore/Items.data and ~/Library/Caches/com.apple.findmy.fmipcore/Devices.data in JSON format. The app periodically reads these files and stores a new record for each device if there is an update.
