This app collects a bare minimum of information from users. Dual Heights Software AB do not collect or sell any identifiable personal information through the installation or use of the app.
The app requires two permissions on your Android phone; Internet connectivity and Billing. These two are only used by Dual Heights for the optional in-app purchasing. In-game purchase is not required but will remove the time limitation on how often you may open new chests. Dual Heights do not get access to any personal identifying information from purchases.
