JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
For a Free/Starter account, you have 100 MB upload storage and 500 submission storage. These does not reset every first of every month, unlike the form submission count.
If you are referring to the submission storage in your account, it is the total submissions stored in your account for all of your forms.
If you have more than 500 submissions in your account, the oldest submission will be deleted when you receive a new submission in any of your forms.
You can free your submission storage by deleting submissions through the submission page. However, we recommend you download your submissions first before deleting them because once a submission is deleted it cannot be retrieved.
I hope the information above helps. If, in any case, I have misunderstood your concern or you have any further question, please feel free to contact us anytime. Thank you.
