Intel AppUp® center supports applications submitted with product keys. With our current policy you need THIRTY-FIVE (35) product keys in order to validate your application and at least ONE (1) additional key so that the app remains published in the store. However, we suggest adding product keys to a level that creates a comfortable buffer to ensure you don’t run out of keys. You can submit up to 1,000 product keys. Your app will be automatically unpublished when its keys fall below ONE (1) key and will be republished once you upload more.
E-mail alerts: You will receive an email warning when you have just FIFTY (50) keys left. When the number of product keys has dropped to ONE (1) you will get a notification requesting that you load additional keys. If the number of keys drops to ZERO (0) your app is unpublished.
Learn more about how to manage your application keys in this article.
Please feel free to post your question in this forum thread if you have any doubts about the product key policy.
