Imposition Wizard may ask you to collect some statistics about the imposition jobs you perform. This includes things like layout parameters, paper sizes and so on and doesn't include any personal data like your name, location or hardware information.
We'd really appreciate if you allow us to collect such information for further analysis. This helps us to focus on the most used parts and features of the application, so we make it even better with each new release.
You can always disable (and enable) statistics in the application's settings menu.
