it's just a normal mod, all it does is collect some data and save it in your WTS/Account/<Account Name>/SavedVariables folder. Same as all the mods do.

The second half is an html page with some java script to read and understand the data contained in the mod's saved lua file, and display it nicely.

There is nothing in there that is a problem for Blizzard, not sure what part you are afraid of.
The scripts are currently in working order, i'm just finalizing some error message and polishing it a bit before making it available.


The catch, and some might not like it, is that it is Impossible for an online web page to read a file on someone's computer (for obvious security reasons, except browser cookies), so the only way i found to make this work, is to provide an html page to copy on your machine.
I know some people won't like that part, but heh, the code is available for all to see (reason why i didn't want to do it with a java app) and if they don't like it they don't have to use it :-)

So in the end, I have the addon that i copy in the normal addon folder (WoW/Interface/Addons) and the html page that I copy in the WoW root folder, and call through a browser.
Since the WoW folder is parent to the WTS folder, the html page has rights to read the files there and it all works like that.
