Nope. We care deeply about protecting the privacy of our users.
First and foremost, Hawkeye does not and cannot perform eye tracking outside of the Hawkeye app. Because of the way iOS is designed, it is (thankfully) impossible for Hawkeye to be used to track your eye movements in other apps like Facebook or Instagram.
We also make sure to alert you whenever eye tracking is about to occur. Our calibration process means that you actively have to participate in the test before eye tracking can even begin.
