I'm sorry 
I got, but isn't a commercial adv and neither the app is commercial or for commercial purpose, just wondering if someone will find it useful
if you think is not complain to the site rule I'll delete it
(if I can)
Normally, the advertisers we get on this site just come here once, spam their stuff, and leave with responding to any questions. That's why that rule exists.
However, there are instances where the advertiser responds to questions, like here:
https://www.pianostreet.com/smf/index.php?topic=71804In those cases, they do sometimes stay up.
Based on the fact that you responded, this might be one of those special cases. Sorry for the misunderstanding.
