The Brain Defense is committed to making our games both fun and safe to use, and we are committed to best practices regarding the collection and use (really the lack of use) of both anonymous and limited personal information. In general, our approach is to only collect anonymous data wherever possible and use as little personal information as is necessary to provide the best games and services, and then only to use personal information to make those games and services better, mainly through having an email address for communications with our support team. We do not gather or use anonymous data or any personal information to broker to third parties for commercial purposes; we only want to make our games better, and we only work with best in class advertising companies with similar policies. We ask players whether they are under 16 if in the European Union and under 13 in all other territories, and if so we do not collect or store on our servers any personally identifiable information, including IP address. Still wanting to make sure we provide best-in-class customer service, those players are given a non-personal unique code if they need to contact customer support.

Any changes will be posted here, and significant changes will either be broadcast on the The Brain Defense blog and social channels.
