Worldcoin has implemented an individual data stewardship policy, enabling users to control the flow of their personal data

TechFlow news: Worldcoin has implemented an on-device custody policy, announced alongside the launch of World ID 2.0.

On-device custody refers to storing iris codes—information generated during World ID verification such as images, metadata, and derived data—directly on users' devices. This approach enables users to maintain control over how their data flows. In addition to providing greater control, on-device custody unlocks new World ID use cases by enabling facial verification for high-security applications. This verification runs locally on users' devices, ensuring personal data never leaves the phone.
