While Star Chef is a game that is free to play, we do offer the option to purchase in-game currency (goodies, coins and cash) for real money. You can make these purchases through the game itself. And these purchases are completely handled by the iTunes Store and Google Play Store, to ensure maximum safety of your personal and financial information. 

That being said it is very important for us to give our players the ability to choose how they would like to play the game - so every area of the game is equally accessible to players as they level up, regardless of whether they invest real money into the game or not.
