Do you destroy this information once the owner has chosen to opt out?

The reason I, and I suspect many others, avoid these types of services is the risk of this information being inherited or possessed by an entity that would use this information in ways to which I do would not consent nor approve. This information would not only affect me personally, but also my children.

Germans are more privacy-aware than most for a good reason. I dread a future where an evil government gets a hold of this data and the technology to effectively use it.
