I don't think anybody should fork over their private information to any casino platform.

There are literally dozens of alternatives out there that are just as fun, and don't require your private info, like BitKong.com

That said, the project is quite forthcoming about its own details;

"Casino Extreme is operated by Anden Online N.V., a registered company in Curacao. The service operates under license no. 1668/JAZ issued to Curacao eGaming, authorized and regulated by the Government of Curacao."

But they don't actually say exactly how they protect user data, or whether it's kept private and not sold to third parties.
