To allow you to get rewards when you share a game, we provide common UTM links for your friends or followers to use. Refereum also uses the hash technique to make data absolutely anonymous. Refereum hashes do not contain any personally identifiable information. Unlike Facebook, Google, and most other websites, 100% of Refereum UTM data is both anonymous and encrypted. Even though the vast majority of people would never care about the random letters and numbers, Refereum also instantly encrypts any content in our databases (which are as secure as most banks).
