Google says it doesn’t use your Gmail to show you ads and
promises it “does not sell your personal information, which
includes your Gmail and Google Account information,” and does
“not share your personal information with advertisers, unless you
have asked us to.”
But, for reasons that still aren’t clear, it’s pulling that
information out of your Gmail and dumping it into a “Purchases”
page most people don’t seem to know exists. Even if it’s not being
used for ads, there’s no clear reason why Google would need to
track years of purchases and make it hard to delete that
information. Google says it’s looking into simplifying its
settings to make them easier to control, however.
I’m sure they’ll get right on that.
