Please contact the app store provider first, if you experience any problems with a purchase of one of our apps or in-app products, or if you are unable to re-download an item you have purchased. This is important because all purchases and subscriptions are handled by the stores. We only offer the use of these services in our apps.


If the store support cannot find a solution or subsequently refers you back to us, we will try to help you as best as we can.
