The user would still have the opportunity to use the app or the operating system, or whatever it is that the cellphone covers, if that's what they are signing up for. When they say opt out, they opt out of that aspect of it, but they can still have it, so they are not under any type of duress to sign up.
We also have the case of the Tim Hortons app. Users were told that geolocation functions were only being accessed when they had the app open, but it was later learned that the app was collecting information even when it wasn't open.
Do you see the role of the Privacy Commissioner as having anything, again, to pre-empt such an aspect? In particular with this one, nobody can cash in their points unless they download the app so they say, “Okay, I can't have my points unless I give them access to this information.”
