These options allow you to enable logging of activity to a CSV file that can be imported and analysed in another application (e.g. Numbers or Microsoft Excel)

Log location

Note: Due to the requirement for App Sandboxing, you must click Choose... to choose a location for the files to be stored, otherwise PeakHour will not be granted permission to write there.
