Prevent apps from showing your name

On iCloud.com, you can see a list of the iOS, iPadOS, and macOS apps that let other users of those apps look you up by the email address associated with your Apple ID. Anyone who looks you up can also see your first and last name.

Note: In some locations, you can use a phone number instead of an email address as your Apple ID.

You can prevent any listed app from showing your name and email address to other users.

On iCloud.com, go to Account Settings, then click Manage Apps That Can Look You Up in the Advanced section.
To prevent an app from showing your name and email address to other users, deselect the app’s checkbox in the list.

If the Look Me Up By Email list is empty, you don’t have any apps that use the feature.
