Default Where does SoundHound saves its files?

Im dealing with this error "unkown error -24" after trying to install SoundHound ∞ from playstore. I had it installed before and trying to install back and cant get around to do it.

There's many threads on this saying I should delete files from previous installation, I already tried deleting data/data but I cant find or anything. A search for "soundhound" on my whole SDCard comes out empty.

Where does soundhound saves its files?
