Today I deinstalled and re-downloaded the app. To restore my settings. When I called up the list of my airplanes, some of them I bought were missing. I’ve looked at the Google Play store but there was no invoice. So I thought that the money must be back on my GoogleAccount Credits. But it was not! What a rip off.
You cannot be charged for any previously purchased item twice (except a Live subscription) unless a different store or account ID is used, or the item was refunded.
Modified devices like Jailbroken or rooted do not necessarily apply to that rule. :)
GooglePlay cannot charge you twice for the same content unless you used a different store ID or were refunded. If you were charged, then either the store ID is different, not yet purchased or it was previously refunded.
That’s true however in a rare case it’s possible but it’s very unlikely with an in app purchase and if it happens it will happen with a paid app you already have
