You either rig your individual PC to use their DNS servers or – more recommended – rig your home router to use their DNS servers (and all your network PCs then get it, too). So, at most, it’s a config setting. Second, stat tracking is only available if your register for a free account, which includes identifying your network’s IP address on the Internet. So… point is, the only violation of your privacy was done by you… or your network admin. Either way, it’s not OpenDNS’s fault.
