You could add a noindex if you think the privacy and disclaimer pages, etc, are not bringing any SEO value. Nofollow would block search engines from even spidering them. But a noindex would just stop it from showing up as an entrance/landing page in the SERPs.
I wouldn't say that it helps "retain link juice", but it might help you to show the search engines what your most important pages are.
An alternative would be to perhaps only link to some of those pages from your home page and not from every single page. Are there any pages that you think would be appropriate NOT to link to all those pages? If so, perhaps you can write a conditional statement in your code to only show those links on some pages and not others.
