> this means sharing your 3D likeness with some sketchy American business who pinky promises to delete said data after. I don’t want random American tech companies to have my kids’ biometric info like that, able to sell it to whoever asks. Nor my passport or anything like that.

Actually the market leader app for scanning faces and documents is an Israeli company. They encourage to use mobile for scanning, for your convenience. They promise they delete the data. Yeah, if they're lying you can sue them in Israel.
