I want to delete all my data and start from scratch.
You have the ability to delete your data in TrackVia Express by clicking on the database icon on the top right of your screen. Then choose All Apps from the menu. On the next screen you will see the apps you have created and each app will have a trash can icon so it can be deleted. This will remove all of your tables and records from the app, allowing you start from scratch.
