Hi Gale, The free trial will automatically end after 7 days. We do not ask for card details when you install the addon/create your account. So you don't have to worry about getting charged automatically. 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 in the top right corner > click Addons > search for Neartail > select Neartail > click on Uninstall. If you would like to delete your account, please send an email to support@formfacade.com.
