MacCleaner – Too clean?

The other day, I went looking online for a nice, freeware program that would help get rid of unneeded files on my mac. I’d been organizing things on it lately and I figured that was the next step. So I ended up coming across MacCleaner. (EDIT: Original maccleaner site seems to have been taken down. You may have trouble getting a “registration key”. You still might be able to find the app with a google search, though.)
