The official reply was already given multiple times. As I said before, our game is secure against cheats. No one can obtain Units, in-game currency, Resources or Items in an unfair way. You can receive them only for your in-game activity or in-app purchases.
There are no working cheats that give you free Units/Sapphires for Stormfall. If someone claims he has one, he is spreading false information. If someone shares such programs, it's usually phishing that is aimed to get your game login and password (steal your account), and it doesn't work the way they claim it to work.
We strive to protect personal information of our players while it is under our control. To help protect the confidentiality of personal information, you must keep your password confidential and not disclose it to any other person or for using such sites.
