An old school chum that, i used to roll with , but , moved away long ago has , been : keeping in touch with me on skype for a couple of years now. He makes Android mobile device games independently , selling them through two cosigners : Google play® , and , Amazon® app store. He roped me into helping him on a recent project of his , in agreement for : a percentage of his earnings from the app in perpetuity. This arrangement was confirmed by email. It is a Halloween pumpkin game, so, it will make a small amount for each year its posted, as search traffic perennially returns to its seasonal keywords. I proposed the idea of : pulling it in early November, and , re posting at the beginning of next October , so , it appears as a new app each year. He didn't seem keen on that, because , he proclaimed that : even bad, outdated , or unpopular apps get an occasional download , and , the more apps/games he can keep on offer , the more prosperous he looks to customers. Sadly, i am suspicious that, he is not being honest about the apps sales figures. The first sign of trouble was : I notice , on every google play app page, there is a stat at the bottom called "installs", google play does : automatic installs with download , so , this pretty much says how many sold. On this particular page it does not appear. The lowest threshold to display the stat is : only one install. When i confronted him on this , he claimed : it did not sell one single copy from that cosigner. He also claimed that it only sold a scant few on Amazon, only enough to make my percentage under $1 (USD). Amazon does not display an "installs" on the user page. Installs also don't appear in "app annie" (analytical tracker for detailed mobile app stats). I suspect, he is hiding the stat in his own options , and , not being honest with me about the real sales figures to : weasel out paying me a few bucks. While he is an old friend , he seems to want to move off the subject of telling me the excact sales when , i try to bring it up , but , so would i , if things were going so poorly , and , my partner was asking about percentage. I have remembered a few contradictions in his chat from : before we worked together , during collaboration , and , after publish, that , while innocuous in of themselves, added together with : the missing install stat ,and , general vagueness about actual sales, adds to a mounting pile of circumstantial evidence. Its hard to tell if he is hosing me or not. It wasn't a strong app. He made it a rush job , so , while his coding was not buggy or anything , the actual content quality wasn't as good as it could have been. To be honest : an unoriginal game without good playability , but , pretty skin, 3-d texturing , and intricate sprites to give it an illusion of its non-existant depth , so , its possible that the game didn't sell. However, its hard to swallow that : it didn't sell one cotton picking copy from google last month. Thing is : we do have a long history , and , i want to give him the benefit of the doubt. If i was working for a stranger , and , it got like this, I would be demanding dashboard screencaps at this point, but, because of the long standing history , i don't want to come off like a dick. What i just said right there , is , almost verbatim : the cadence of a con man victims story, its always like : they know their being hosed in their core , but , the con man always has some type of leverage that , keeps the mark just barely committed enough to : hope against hope the lies might be real. He is an old friend , but , i would love something concrete to hold him to his word. The agreement email, i have on file is : legally binding , emails have been proved binding by court precedents as contractual. The email gives me little leverage to keep him honest if : i can't verify his sales , and he knows it. I am far from talking to lawyers for these small potatoes , and , he knows that too. Am i hosed or not? Is there a tactful and polite way i can ask for sales record documentation? Is there a different analytical tool that i could use to find the actual downloads history on my own? Would the cosigners provide download statistics if : i inquired as an interested party?
