Does your Cell phone service provider have your GPS data stored at their database?
This is one of those questions that we are not allowed to know the answer to. I believe if they did store it without permission, it would be an invasion of privacy and therefore illegal unless there was a court order. But in our real world today, we don't know what they are doing. For instance, we have that covid tracking feature included in one of the iPhone updates that will alert authorities if you have been near another person who tested positive. Who knows what else it is capable of?
It's for our own good, of course...
