Monthly form views and submission storage

And also I would like to ask about the plan.

What is 1000 monthly form views? How does it count?

What is 500 total submission storage?

Form view is sometimes referred to as impression and it is any type of loading the form. Each time someone loads/accesses your form, that would be a form view.

If someone goes to edit their submission - that is another example of a form view.

You may refer to this page for more details about it: form-view-limits:-what-is-it-all-about?

While the 500 submission storage is the maximum submissions that your account can store. This increases based on the plan you're subscribed to.

So for example, you already reached 500 submissions and you received a new submission, it will remove the older submission to make way for the new one.
