The rules only require developers to allow users to initiate deletion of their accounts, so apps can still direct users to a website or chat before users can actually close their accounts.

The system only works for group sizes and activities for which it has been trained and it requires a high-resolution camera. Many side-channel attacks are impractical for real-world use, especially when most surveillance targets already carry smartphones or use smart devices.
