Two or three guided photos
The screen guides you: face straight on, well lit, at arm's length. You take two or three photos. Several photos beat one, because we keep the middle value of each measurement: a bad photo weighs less.
What your phone does
A face landmark model runs in your browser and places 468 points on your face. We serve this model ourselves: no third-party service is called during the scan.
The pose gate
Before measuring, a gate checks that your face is straight on. Turned, tilted or raised, it is rejected, because an angle changes the measured distances. If the screen rejects your photo, face the lens again with your chin level.
What leaves, what stays
Only numbers go to the server: the coordinates of the points, from which it calculates your rating, and the sharpness of each photo, which is part of no rating. The photo stays on your phone.
