It was for a family friend who is disabled and unable to work a normal job, so me and my brother(also a dev on this) agreed to be paid on project completion. Long story short, she wasn't able to pay so the final bug fixes were never done, and the code has been left to rot. Under different circumstances I'd be putting pressure to get at least some payment, but it's pointless imo.

Lesson learned though, not doing that again.
