Remove logo in paid subscription

Also if I upgrade to a paid subscription does your logo disappear on the forms ?

If you are referring to the JotForm branding the answer is "Yes", disabling JotForm branding is only available on paid accounts. 

Here's a guide on how to remove the branding if in case you upgrade to a paid subscription.

1. Go to your account settings: https://www.jotform.com/myaccount/settings

2. Scroll down and look for "JotForm Branding"

3. Uncheck the "Show "Powered by JotForm" on my forms", this will remove all branding to your form.
