Yes, whilst you do have a telemetry box, it is not phoning home. Data must be actively pulled from it by hand. As you know, typically this is done after an accident to better tell what the car went through. I know there are people who have sought to disable the boxes, but I don't know the legal or insurance ramifications of doing so. It is also difficult to locate them as they are "hidden" in the mass of wiring and other components. There are probably manufacturer-specific auto forum discussions on the matter to refer to.
