At first glance, this appears to be a very powerfult betpot application for iPoker. It is not, as the OP suggested, an AHK - I guess this is a language barrier thing
As with all software provided without source, no-one can "confirm" this is safe. Just as no-one can confirm it is not, unless they have been hit and are expert enough to know how.
This is why we like AHK - any script code could easily steal passwords and send them to internet thieves - but the visibility of the code means one of us will likely spot it quickly, and hopefully crisis averted. In the end however, it is down to the user to understand the code they are running if they want to be 100% safe. With a compiled EXE, there is not an easy way to do this.
Now, I'm 99% sure this is fine - but no-one is going to come here and guarantee it is safe - and if they do, they are either the author (and if you trust them telling you it is fine, you don't need to hear them say it), or they are wrong.
So, try it if you want - it looks superb. But don't expect others to tell you if it is safe or not unless they have been stiffed already
