Yes, Magus and Royale made available their own very useful bunch of CG stats, but they are more oriented on multiplayer puzzles, and I know that there are people like me who still need to track their solo puzzle progression.
That's what my tool is about : Knowing which genuine puzzle you've achieved (100%) and in which langage (because it's always difficult to find it out when you often switch from one langage to another)
So, this tool should be considered in Beta. Please give me your thoughts, suggestions, bug reports, and so on...
(By the way, the possibilities of the tool may look limited, but keep in mind that there is no need to be connected or to get your ID to check for private informations...)
