Worldcoin implements personal custody

World is implementing Personal Custody, a data custody approach recommended by privacy experts that was first announced with World ID 2.0. Under this approach, images, metadata and derived data generated at the Orb and used to create the iris code are held on the user's device rather than deleted by default, giving users control over any future use before deletion. The system also enables Face Authentication, which works locally on the device without data leaving the phone. Optional Data Custody will no longer be offered at the time of an Orb visit.
