> It knows my biometric information; it knows the very contours of my face.

I was under the impression that Face ID does not leak such information to whatever app is using it?

No, FaceID doesn't leak informations about your face. Just like TouchID doesn't leak your fingerprint.

This has nothing to do with FaceID, which isn't mentioned in the article.

WeChat has its own face recognition system.

Ah ok, i thought the author meant FaceID in the passage:

> I have my WeChat linked with the facial recognition scanner on my iPhone

was not aware that WeChat has its own system. They don't get to use the "special" FaceID sensors/scanners though right? Just the camera?

It looks like depth data can be accessed through the AVFoundation framework provided by Apple.

No, WeChat and Alipay do use FaceID to do payment verification on iPhone.

Maybe they do but at least WeChat have their own face recognition technology, in which case they do hold people's biometric data.

This is not that big a deal in China considering that people have photo ID card, which means that the government already had everyone's biometric data.
