I bought an android app " MintReward "
I contacted my developer to customize it, but he told he can just reskin it because the main jar library is encrypted.
I asked the seller he told that “We cannot expose the library that are being shared with you all customers. It will affect other customers” and He told me if I wanna customize it, It will require both app source code and backend customization with extra charge.
I found also that every time the user open the offer page there is a request send to this link
how do I know you didnt put his offers there?.
he answered :
That url is just a hit counter.
If I wanna add offerwall networks I have to pay him …
the resume is I bought a code I can just reskin it, I cannot add function like I want.
My Question is : is it ok to sell apps contain encrypted part ?
