Well for one it’s not the normal camera it’s the face scanner that’s actually does the scanning as it scans the environment when you use the phone.
Just remember you’ve given Apple your fingerprint, face scans & voice.

You realize face ID works on a seperate coprocessor severed from other components connected to the internet?
That I can use with my other internet connected apple devices right?
Elaborate.
Ok so I have my Apple ecosystem set up to always ask to buy/download prompt face scan on my iPhone. Any of my Apple TVs, macs, so those devices have access to the face scanner even tho it’s not connected right?
They get a checkmark. The face scan is not being passed onto anything connected to the internet.
