Those things are under open-source license. You don't need to credit them. My code was not under any license and you should have asked me before you copy it. I also noticed that you have copied unrelated files from my repository which are totally unnecessary for the TIPPER to work. This means that you do not have enough skills to implement something like this on your own. Yet you're taking credit for your "hard work" in the comment section and you're now promising not to use my code but implement your own(yet your app is still using mine). I doubt you can implement your own after looking into how you've copied mine.
