Hi again,
Thanks for contacting us.
We are so sorry for the late response because we took part in a long national holiday in our country so we cannot help you during that time.
For your question: When users register or login to your website, the system will save their email automatically so the contact information will show the email address. Therefore, the email address will be stored on your website. We are really sorry but there is no way to remove it from your website.
In this case, you can hide the email address which displays on the front page but it still saved normally.
Best Regards,
NooTheme
