There is a data protection issue here, isn't there. The collection of

together. If you are really worried, I suggest you ask them explicitly.

You can be tracked all over the place by several means. Mobile
'phone, security cameras plus face recognition, credit card use ..
doubtless more I haven't thought of and more to come in the future.

Learn to live with it. It's useful in tracing wrong-doers. It isn't
going to go away.
