Apple does not track such data.
So they say.
Even if they don’t, who’s to say the apps’ creators dont have something in there that’s accessible to govt sources.
Just this past week a bunch of apps were pulled off platstore and apples store that no one knew about that were actually malware searching for useful info on peoples phones and tablets. Apps that have been out there for years.
Remember the nsa’s project x-keyscore, intercepting cisco routers and putting in backdoors for accessing traffic.
It would be naive, given what does go on that is known, to simply,believe nothing will happen to this data or that no one collects it. Apple may not, but I would bet it is being collected by someone.
