In some areas like this one, control is just an illusion. You can certainly do things to reduce and risk manage the downsides, but you can only ever do so against scenarios you have dreamt up and spent time confirm and validating that your solution works. Its an endless amount of work that isn't sustainable. The only way to ensure the data collected can't be used against you now or in the future, (i.e. isn't stolen in some way), is to not collect it in the first place.
