Slimjet only collects some anonymous feature usage statistics information. The sole purpose of doing this is to determine what features in Slimjet are popuplar among users and what features are actually rarely used. We will use such information to improve the software and optimize the user experience. It will help us to determine how to best allocate our development efforts among various aspects of Slimjet.
When we say "anonymous", we mean we don't performanently store the user's IP information on the server (Many large advertising companies use IP address to track individual users and send targeted ads, which is not truly anonymous). The collected usage data is only used internally within FlashPeak. It will never be shared with any third-party organizations.
Such anonymous usage statistics collection can be easily opted out by the user by changing the option settings.
