About these terms
These terms cover the Mass Reaction game for iPhone and this website, massreaction.app. The game is developed and published by Yulia Shishkina, an independent software developer in Luxembourg (“we”, “us”). Questions? .
The game licence
Mass Reaction is distributed through the App Store. Unless its App Store page names a different licence, your use of the game is governed by Apple’s Standard End User License Agreement. These terms add to that agreement and do not replace it. Apple is not responsible for the game or its support; we are.
Optional purchases
The game is playable without paying. You can optionally buy packs of special balls through Apple’s in-app purchase system. The contents and price of each pack are shown in the game and confirmed by Apple before you pay.
Special balls are consumable: a ball is used up when you put it into play. Your stash is kept in the iCloud account of your Apple ID, so it follows you to other devices and survives reinstalling when iCloud is turned on. If iCloud is off, the stash exists only on that device and is lost if the game is deleted. Special balls have no cash value and cannot be exchanged or transferred.
Refunds for purchases billed by Apple are handled by Apple. You can request a refund through Apple. If a purchased item does not arrive in your stash, contact us and we will help.
Gifts and game changes
The game gives some special balls for free along the way. Which special balls appear, how often, and what is gifted or offered may change in updates as we balance the game. We will not take away special balls you have already bought.
The leaderboard and fair play
Mass Reaction has one shared Game Center leaderboard, and it includes runs played with special balls. Please play fair: scores obtained by cheating, modifying the game or exploiting bugs may be removed.
