Where are the original UFW rules sourced from?

I don't mean the files under /etc/ufw/, as best I can tell, because I have rules with comments in them and those comments do not exist in any file in that directory. The .rules there are the derived commands for iptables, and their comments contain only the app name. Say ufw status numbered shows this rule:

To                         Action      From
     --                         ------      ----
[ 1] MyAppName                  ALLOW IN    Anywhere                   # myuniquecomment

MyAppName is defined under /etc/ufw/applications.d/ but I can't find myuniquecomment except in the output of ufw commands. So where are the originals located?
