According to Odaily Planet Daily, people who have registered for World ID can request to delete their iris scans, and the Worldcoin project said it would do this after a six-month "cooling-off" period. In addition, the project also implemented "on-site age verification checks" to prevent people under the age of 18 from registering. It is reported that Worldcoin has assigned World IDs to nearly 5 million people, who agreed to undergo iris scans to prove their "personality," or that they are human.
