How long the JotForm servers keep the information so that the users could fill the form at a later date?

would you inform me the duration that the jot form servers keep the
information on the form so users could access the "live form" at a later
date

If the auto-fill feature enabled on the form, the information will be stored in the browser storage. So,  the information can be accessed only when the form is re-opened using the same browser on the same computer. If the browser cache is cleared, the data on the form will be lost.

If you are using the session parameter method, the information filled on the form will be stored in the JotForm servers for 90 days.

Hope this information helps! If you have any questions, please let us know. We will be happy to assist.
