Are you using your phone photographs to track my movements? I don't care about the photographs part, I care about the "collecting data that can track my movements" part.

I don't mean my movements on the internet either. I understand that those things are easy to track. I mean in real life.

As far as responsibility for the data goes, you're right, it's not clear. Therefore, anyone who uses the data -- Flock or their customer -- should be required to delete it on my request.

That seems like a pretty clear delineation, no?
