They got your IP Address, which just means they have the number that corresponds to your device when it accesses the internet (for most people in most situations, this number changes often) and it doesn't really do much besides tell them the general location of the device based on the numbers themselves as they pertain to a location with how they're assigned. But they're general enough to be mostly useless. But enough to spook some folks.
But, was the thing about urine in your second to last sentence a mistype or did you mean that?
