Formesign is a paid product with a free trial. When you install the addon, we automatically enable the 7 day trial. You get the first 20 responses free during this trial period. If you find Formesign useful and would like to continue using it after the trial ends or collect more than 20 responses, you can subscribe to the paid plan and use Formesign. Note: - We do not ask for your card details when you install the addon. So you don't have to worry about getting charged automatically. - You will have to use the Formesign share link to collect responses. Otherwise, signatures and customization will not work.
