The Worldcoin cryptocurrency project has promised to stop independently storing the personal data of its 4.5 million users. The practice of collecting retinal fingerprints in exchange for tokens raises questions among law enforcement.

The crypto project plans to introduce a Personal Custody system, which will allow images and any metadata collected by the Worldcoin Orb device to be stored on users’ gadgets.

During data verification, World ID Orb will have to process the images directly on the device and transmit the information to the user. The company has been working on the Personal Custody project since December 2023. Thanks to self-storage of data, users will no longer need to store it on Orb or upload it to the company’s server, the project team promises. Customers will be able to consent to the Worldcoin Foundation sharing their images for a greater level of security.

The measures were taken by the Worldcoin team due to criticism of the project by government authorities in Germany, South Korea, France, Kenya and Spain. In March, Spanish authorities expressed concern that the project was illegally collecting information on minors, after which a court blocked the project's activities in the country.

In December, Worldcoin promised not to verify customers using the Orb device in Brazil, India and France. At the beginning of the year, the crypto project announced a new, “friendlier” device for scanning the iris of the eye.
