PPSE is open source software for editing the save files of the 4th generation Pokémon games. The goal is to replace current save editing programs that are not open source and are lacking in many respects.

This software's sole purpose is to enhance the Pokémon game experience of the players who chose to do so. While we will try to make it possible to edit saves in such a way that there would be no difference in doing something in the game vs doing it with PPSE, we cannot guarantee that this will be the case.

Either way, we believe that players who choose to use game enhancements such as PPSE should in no way interact with players who want to keep their games, cheat-free. We cannot force anyone to abide by this. However, it is our hope that those who choose to use this software will do it in good faith and respect the wishes of other players.

Don't ask whether PPSE leaves any traces. We will not leave any intentional traces, but there might be some left due to the fact that we do not know everything about the saves. Also if you are worried about being caught cheating, don't cheat. Then you'll have nothing to worry about.
