... "We are glad you made it in last week." ...So how do they know this? When you go into the gym you have to swipe a RFID card. But surly they would not save this data with my name attaced to it. So let's say I would hack the system I would know when every member of the gym would visit it. Looking for somewhere on their web page (http://www.fitspacegyms.co.uk) to see what they are actually saving, I found that the page about the privacy police does not exist (http://www.fitspacegyms.co.uk/privacy-policy).
This feels a little like 1984. I can't wait till they send me advertisement suited to my training plan after FitSpace has made a lot of money selling this data to some other company. (This would not even be illegal)
