Habitrak Habitrak has been the flagship product for affiliate software for the past several years. Almost 50 percent of US Affiliates have purchased Habitrak during this time. However, with the transition of Habitrak from HFHI to MoreThanData in 2006, MTD has renamed the product and implemented a host of new features and improvements to help you fulfill your mission. As a result of the transition process, the name 'Habitrak' is no longer being used. Instead, Habitrak is now called 'Keystone'. With the release in late 2006 of Keystone 5 - a major upgrade to Habitrak - previous versions of Habitrak are no longer being sold. MoreThanData discontinued support for Habitrak versions 4.x and earlier on January 1, 2008. Versions using Habitrak's new name - Keystone - will continue to be supported. We encourage Habitrak users to upgrade to Keystone 5, which has numerous improvements and new features. The upgrade to Keystone 5 is free to all currently-licensed Keystone users. For more information about Keystone 5, see our Keystone section. For additional information about why system requirements have changed, please refer to our Keystone System Requirements section.
