If a U.K. user has not already signed up for Advanced Data Protection, they will not be able to as of February 21, Apple said. Instead, those users will see a message: “Apple can no longer offer Advanced Data Protection (ADP) in the United Kingdom to new users.”

The service will no longer be available to new users and current U.K. users will need to eventually disable the security feature, Apple said.

Apple is taking the unprecedented step of removing its highest level data security tool from customers in the UK, after the government demanded access to user data. Advanced Data Protection (ADP) means only account holders can view items such as photos or documents they have stored online through a process known as end-to-end encryption.
