Why data is processed
Data is provided when you enter this agreement with the administration, and when the Service asks for it in order to carry the agreement out. That includes creating a master account, taking part in tests or events, contacting support, and using extra services inside the game.
The Service uses that data to create and manage your master account and linked game accounts, to let you play and use game features, to let you interact with other players, to fix bugs and build features, to answer support and send notices about the Service, to accept and check payments, and to tell you about events and updates.
