Hi - We do not ask for the card details when you install the addon/create your account. So you don't have to worry about getting charged. The trial will automatically end after 7 days. If you have installed the addon and would like to uninstall/remove the app from your Google Forms, here's the instructions: Open your Google Forms > click on the three dots icon next to the SEND button > click Addons > search for Formfacade > select Formfacade > click on Uninstall. If you would like to delete your account, please confirm.
