Wha...? Is that satire? You realize Google's primary line of business is that they DO collect every bit of data on us imaginable and store it forever? [Then sell it.]<--Editing this to more clearly reflect that they plumb this data for advertising profiles and other research, while reserving the right to sell their information (about you) directly.
Search history, browsing history, where you physically go [maps], your social circle, your family circle, your demographics [age, race, sex, income bracket, geographical location, who owns your address, where you work etc.] What genres of media do you watch, who calls you [google call forwarding], who is in your pictures [google photos]. How do your patterns differ now from 5 years ago. They even have a sister company that is building a genetic profile on everyone indirectly and directly so they can sell your health risk info to insurance and target you with custom pharmaceutical advertising.
Did you think all their free services were free?

FYI, Apple doesn't care about your privacy. When you sign up on the iPhone upgrade program, their partner (Citizens One) gets access to your bank account, your home address, phone number, data on where you spend money, and many other personal details.
