Earlier quoted context omitted.
"Google" "private"; unbelievable someone can put these two words in same sentence. Google cannot even pull pages older than 10yrs old at the moment.
Google cares a lot about protecting user's privacy. Take a look at their privacy policy. For example, what other API provider requires you to get security audits ($15k-$75k yearly) when handling sensitive user data.
google absolutely wants to protect their users privacy from third parties. their ideal situation would be if they're the only one's knowing everything about their users so they can allow third parties to advertise things to their users. if they'd leak any of this information, they'd be compromising their main business model.
so yes, people can trust google to do their everything to keep their information from reaching anyone else, including forcing said third parties to undergo paid audits to verify that nobody is leeching their user data.
for some reason, a lot of people got it into their head that google literally sells information. i'm not sure why this ever started, as - at least as far as i am aware - google never tried to do anything even remotely like that
