Kinda paranoid... But if we really want to blow your mind.
They also know your exact location, mapped with Google maps, understand your connections, recognize how you write via your email and docs. Sure they don't know the inside of the building you are in or even inside you (although they will soon I'm sure).
Now for the most horrifying... They have access to every Android phone, and they can listen to every single one if they wanted to. If you use Google voice, they can even "learn" your voice. Eventually, they can probably pick you out among the millions or billions of voices.
Combine that with your Google searches, a convolutional neural net over all your selfies... Now sprinkle in some Android wear data and they literally have all of you.
