Worldcoin stores the biometric data for opt-in users. They say it themselves. It’s stored “encrypted” which means the original data is retrievable, and kept in Worldcoin’s custody. All Worldcoin claims is that it has safeguards against retrieving the data it does collect and store, like say Equifax or 23andme claim about your PII.

It sucks and the other uses also suck.

But it's a fuckin scam. It's exploitative, and sleazy as fuck. It uses crappy blockchain tech, the orbs are proprietary, and you really ought to think twice before condescending at people who try to help you out on this.
