The user name you choose for yourself is saved in a database on the smart phone or tablet, so the application can keep track of exercise results for your own viewing. Names and exercise results are not transferred to any other system.
Halfaday Enterprises' mobile applications use Google Analytics to collect limited and anonymous statistical information, including screen information about your smart phone or tablet, geographic location, and how the application is used.
