When first launching Fly the Line a pop-up message will appear asking if you consent to Fly the Line tracking your app usage to help improve the Fly the Line software in the future. 

If "No thanks" is selected, no data tracking will occur, and almost everything related to Fly the Line will be stored locally on your PC. The only online interactions will then be maps and any AI API calls.

Analytics and Logging options in the Settings menu of the Fly the Line app allow this to be changed at any time.
