Do I trust Google to do the right thing? Hell no. Do I trust Google legal to not directly lie to me? I do.
> Google Public DNS stores two sets of logs: temporary and permanent. The temporary logs store the full IP address of the machine you're using. We have to do this so that we can spot potentially bad things like DDoS attacks and so we can fix problems, such as particular domains not showing up for specific users.
> We delete these temporary logs within 24 to 48 hours.
> In the permanent logs, we don't keep personally identifiable information or IP information. We do keep some location information (at the city/metro level) so that we can conduct debugging, analyze abuse phenomena. After keeping this data for two weeks, we randomly sample a small subset for permanent storage.
> We don't correlate or combine information from our temporary or permanent logs with any personal information that you have provided Google for other services.
