The videos are never associated with a user's identity and are deleted after the verification process. Audio is never recorded.
I actually believe them. It's gonna start out this way. But in a year or two, they'll quietly slip in a provision stating they will hold on to the images for a short time for security purposes, then they will say that they will associate your image with your identity to make it more secure, then Google's AI will know everything about everyone (and sell the info to the highest bidder)
