How do I leave Halo Insider?

I have a problem. I joined Halo Insider even though I’m not 18 on accident. How do I leave Halo Insider in order to comply with its rules.

This is on the signup page:

“You may opt out of the Halo Insider program at any time by updating your Halo Insider settings.”

Have you gone into Halo Insider settings and looked there? If the option isn’t there, it should be reported via the Halo Support website.
