Privacy Policy

I'm trying to sort out the privacy policy for my website. I'm using the standard wordpress one and just tweaking it in places. Is there anything I need to change for wpdiscuz especially? Like does it collect different data / in a different way to the standard wordpress comments? Would this statement cover it?:
When visitors leave comments on the site we collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection. An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: https://automattic.com/privacy/. After approval of your comment, your profile picture is visible to the public in the context of your comment. I just wanted to double check!
