Apple is facing a proposed class action lawsuit alleging its “Hide My Email” feature failed to conceal users’ real email addresses from websites and apps.
The complaint, filed Wednesday in federal court, also claimed Apple was aware the feature, introduced in 2019, was not working as early as last summer and did not take sufficient action to fix it.
The alleged issue still has not been remedied, according to the suit, even as Apple continues to claim “Hide My Email” generates “unique, random email addresses” that forward to a user’s personal inbox so their real email address is “kept private.”

“A vulnerability in the implementation of Hide My Email allows almost anyone, without elevated privileges or insider access, to link a Hide My Email alias back to the user’s real email address. Independent testing found that 100% of the aliases examined were exploitable,” according to the lawsuit.
Apple offers “Hide My Email” in two ways: through Sign in with Apple, where users can mask their address when creating accounts online, and through paid iCloud+ subscriptions, which let users generate private relay addresses more broadly.
The lawsuit was filed by Anthony Alvarez, a San Diego resident who claims he was “one of the millions of customers” who paid for an iCloud+ subscription with the expectation that his email address would be kept private.
The feature, as advertised, protects users from spam emails, stops their data from being sold to data brokers and prevents their information from being exposed in a third-party data breach.

A security researcher found a flaw in the feature in June 2025 and reported it to Apple, per the lawsuit.
One month later, Apple acknowledged the bug and by March, Apple said it had “addressed the reported issue in a recent system change,” the lawsuit said.
After the researcher told Apple the bug was still present, the company said in May that it would release a patch within a few weeks, according to the suit.
That never happened, the lawsuit said, which prompted the researcher to go public about the “Hide My Email” vulnerability.

If the judge agrees that thousands — or potentially millions — of people were affected by the alleged security flaw, the lawsuit could move forward as a class action.
The lawsuit does not demand a specific dollar amount in compensation but seeks money for customers who paid for Apple privacy protections that allegedly did not work as promised.
Fox News Digital reached out to Apple for comment on the lawsuit.
