title: Does Android check other accounts registered on device to determine if IAP is already purchased?
body: <p>I'm developing a game at the moment and am implementing In-App purchases (IAP). In my testing I am able to make purchases and then when I try to purchase it again Google tells me I already own product - which is good, of course.</p>
  
  <p>Then I cleared cache, data and uninstalled the game, I go back to the Play Store and switched to my other account and installed the game again on the second account (IAP not yet purchased on this account) but when I go and purchase it it still tells me that I already own the product. </p>
  
  <p>I also tested it on another device which only has my second account - and the product is indeed not purchased on that device</p>
  
  <p>Does this mean Android checks my other account to see if any of the other registered account already owns a certain product? What else might be going on here? </p>
