Seeing as mypermissions.org is just a site with links, i think its just not possible. The most stat that they can get you is the number of people which click on a particular application link (say fb vs twitter)
EDIT: I wrote the above when I didn't know about their chrome extension. That could perhaps be used for more stats.
