The first and last quoted sections are sloppy/bad drafting.
The second is egregious, and embarrassing to be found in a YC company. You should not be asserting rights to how people "link" to you.
Third and fourth basically say any user provided "content" (whatever that may mean) is now "non-confidential" the "sole property of Goodcover", "entitled to the unrestricted use and dissemination of these materials for any purpose".
That sounds like you plan to use some relatively sensitive user provided materials in any way you see fit to advance your company.
But wait! you say...we have a privacy policy! Great, except the privacy policy has an exception...
"We may share information about you as follows or as otherwise described in this Privacy Policy:
...
With your consent or at your direction, including if we notify you through our Service that the information you provide will be shared in a particular manner and you provide such information."
which arguably means that since the user accepted the T&C, they've approved your usage of their materials.
I don't feel you did this maliciously, you probably copied this from some template. Doesn't mean you shouldn't be thinking about this much more carefully though.
