Ill give more info, I'm buying source code to mobile apps, I want to hire people to add very small parts of code and test the apps, so I want an environment with eclipse and xcode, the project files for them to edit. I just dont want them downloading the games and stealing them.
Perhaps I could set up a cloud computer, there are companies that have cloud computing for hire) and give access only to the cloud computer, with no download options for their access. I dont see how they can copy that without manually copying it all.
Or perhaps I just send them part of the code like some have said, Id have to figure out which parts to send them. I dont know where to start on that, and if they only have a little part then I dont think it will work.
The changes I'm looking at duplicating the single player button, and moving buttons to make room, then adding in code for different (third party services) into the home screen for that button.
Possibly adding features for a post high score to facebook, or in game mini games etc, there are lots of services out there to add kinds of features into an app.
If I broke the project down, Im not sure what parts to send, seems easier just to have them work on it on a cloud computer.
I dont have a lot of time, I'm not really into computer techie stuff, I'm trying to expand a business, I have capital to do that, its bad business doing small jobs that I'm not qualified for, that frustrate me, and take time, its just not how to run a business.
But what I am worried about is security. If I buy code it is not cheap, and you have to work very hard to get that money, and I said work, not borrow, and I dont know the people I hire, and even if I did, you cannot guarantee theft, I dont suppose anything is fool proof, but you can lesson dangers.
