To save y'all a click: The alleged biometrics in question are the use of facial-recognition software on photos uploaded to Google Photos (without informed consent from the user).
I remember google popping up a consent to store the AI models for the facial recognition locally on my phone (not in the cloud)! If this is the case, the lawyers are wasting their time, I guess.
UK. I recently bought a new phone and when I opened google photos app for the first time, it asked to store local trained models to enable AI features for the app.
