From their site: RescueTime is built with the idea that you shouldn't have to come to RescueTime.com to view your data, and you should not necessarily have to use our data collector to add data to the system. RescueTime is a web-based time-management tool that allows you to easily understand how you spend your time. One of the coolest things about RescueTime is that there is no data entry. You install a doohicky on your computer and we magically track all of your time usage. NOTE: No API docs publicly available.
