I’m going to deploy new paid app to appstore. This app will connect to our server and download some data (pretty big sometimes).
I’d like to know, is there any way I can check (on server side), that request is going from app, which was really paid (not stolen).
I know that anybody can buy app once and then distribute it (and guys with jailbreaked phones/pads can install it easily). It may cause extra traffic from our servers, and we want to protect us from it.
Or may be I can somehow figure out, that request comes from one sold copy of app? In this case, I can restrict numbers of downloads from one copy, so if it will be widely distributed, it just stops works one day.
Any ideas?
Well there are many tries to detect, if a device is jailbroken. But most of them can be tricked out again. So there is no SAFE method of detecting a jailbroken device. But just search for “detect jailbreak”.
Than you could send your result to your server (together with the data request) and decide, what to do. But think about the effort, as said by Conrad Shultz.
Anyway you can track, how many apps are sold and how many server requests there are. So you will have youre private statistic, how many copies of your app are stolen. You can upload an update for your app anytime, if it really will be a big problem in your case.
