No personal data is sent to our server in any way. Nothing. Zilch. Nada. All the face detection algorithms will run on your own computer, in the browser.
In this ‘test’ your face is compared with that of all the other people who came before you. At the end of the show you can, if you want to, share some anonimized data. That will then be used to re-calculate the new average. That anonymous data is not shared any further.
