I want to downgrade to free option as I don't have very many submissions. Will I still have access to my forms?

Yes, you still will do, but cancelling this grandfathered plan will imply these things:

1. You will not be able to create new forms. Free accounts can only create 5 forms.

2. If you delete, disable or archive one of the current forms you won't be able to restore it or re-enable it.

2. If you want to re-upgrade, the new pricing structure will be $19.00 a month instead of $9.95
