The "hide my email" option when signing up with Apple will create an EarnApp account with a randomly generated email to protect the privacy of your real one.
Please take a look at the options below that suit you better and choose accordingly at the moment of account creation.
Signing up with Apple presents you with two options:
- Share My Email; This option will register an account on EarnApp with your actual email.
- Hide My Email; This will create a unique, random email address that will hide your real one and create an EarnApp account with that same email which should end with @privaterelay.appleid.com
