Data about you is never thrown away
I was quoted by The Enquirer saying that we shall all assume that data (from wearables and otherwise) that is collected by service providers will never be deleted. The data collected by wearables is only as protected as the network that holds it – and it is likely to be stored indefinitely.
“The trend today, given the ever-decreasing cost of storage, is to store data forever. A CIO will prefer to pay a bit more for a little more disk space than risk his job and company prosperity by deciding to discard data that is one day determined to have been useful.”
