Here’s the information directly from the FAQ as of right now:

Q: Is my data stored when I use Face Scan or Scan ID verification?

A: Discord and k-ID do not permanently store personal identity documents or your video selfies. The image of your identity document and the ID face match selfie are deleted directly after your age group is confirmed, and the video selfie used for facial age estimation never leaves your device.

I know they’re kind of a fad, but I genuinely love my Owala. The built in straw means an extra couple things to clean, but it does a pretty good job keeping things insulated and I’ve never had it leak.
