To the people worried about their data being sent to google or whatever (I'm not sure what they're actually worried about) -- the extraction of your eyes is done client side, using a seemingly very well made ML model running on Tensorflow which fits in under 15mb.

The feed of your camera is transmitted "directly" to the person you're looking at (well, no, not really directly, it uses WebRTC, so your data passes through Neal's TURN server, but do you really think Neal wants to take care of properly storing your data and handing it off to advertisers?)
