Do form submissions eventually expire?

Sou MEI, e gostaria que o cadastro simplificado dos meus clientes fossem feito por aqui, mas tenho receio de que possam desaparecer dentro de 1 ano de uso...

Hi MEI,

Thanks for reaching out to Jotform Support. Unfortunately, our Portuguese Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Portuguese, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. Form Submissions data are stored on our servers as long as you don't delete them. Or, as long as the form is not purged. If submission data is deleted we may retain the deleted data on our servers for less than 30 days.

Let us know if you have any other questions.
