I do agree that there might be some privacy concerns over google, but for contacts I actually don't really care.

Lets say I use your service instead of Google, I will protect my contacts from getting into Google's hands (this is only if I don't use gmail/google voice/google plus, which I do so they get my contacts anyways). Now I have protected my contacts, against google. But I have 173 friends/family that also use Gmail. This means that every single one of them probably has my email/phone/address and uploaded it too into Google Contacts. And if I haven't uploaded my contacts, someone else will do it. There is no way of protecting yourself against this sort of social network.
