Simple question:

Why does the privacy policy link in the "about" page links to Twitch's privacy policy?

I've read the Twitch privacy policy and I understand that if a page links there, it should be because it's operated by Twitch, or a Twitch Service. Is that the case of this page?

Is there any plans that this page has its own privacy policy?

On this topic, the site hopefully has a new policy in place that conforms to the new GDPR regulations in place across Europe. It'll be effective starting May 25th.
