tweetnacl.cr.yp.to says

   TweetNaCl is a self-contained public-domain C library, so it can
   easily be integrated into applications.

and the TweetNaCl paper http://tweetnacl.cr.yp.to/tweetnacl-20140917.pdf
says (on page 3)

    We have placed TweetNaCl into the public domain,
    and we encourage applications to make use of it.
