Competition for buyers of iPhone applications & # 8594; How can they prove that they bought the application?

Question

I’m thinking of holding some kind of competition / giveaway for people who bought my application, mainly as a marketing strategy. Buy the application and get a chance to win $ or some prize. Not sure about the legitimacy of all this, but I will test it.

In any case, I don’t have any function in the application to support this or something else (and its already running), so I was hoping that people would just send their order #, email address or something else. But because of his views, although buyers do receive an order from Apple, the seller does not receive ANY information about who bought the application or what their order is, so there is no way to an x-link. Please correct me if this is not correct.

This is in contrast to the Android market, where the buyer and seller receive order # (the buyer via email and the seller through the Google purchasing screen).

Let me know if you have thoughts or ideas that could help. Ultimately, I suppose I can post an update to give users a screen in the app to support this, but was hoping that I could use it without it.

EDIT

Few further studies show that my requirement that people can buy the app to participate in the contest is likely to make the contest considered an illegal lottery. Good: <

Answer 1

In fact, there is no right way besides your latest idea and its implementation inside the application.

Answer 2

Implement a unique promotional code in the application. Use ecid + some magic to generate a short code. The only problem is that you need to update the application.

Answer 3

This may or may not be legal, depending on how you implement it. IANAL, but the competition is considered gambling when they include all three of these elements:

• Prize
• Review (some payment required)
• Variable

Remove one of the three and you should be good. Notice how many contests, for example, the stupid game "Monopoly" passing through McDonalds, always says "No need to buy" and provides a way to play for free. This removes the “review” element from the mix.

Edit: I believe you are in the USA. In any case, this is probably a big question for a lawyer.
