Forms submissions can be saved to many places. For instance you can save your submissions in the Live Forms server's built-in submission repository; store them as email attachments in someone's email inbox; store them into a Google Sheets or a Google Drive folder; store them into a document management system or ECM system such as Confluence; store them into a database or other 3rd party system such as a CMS etc. The options are really endless.
The submissions repository UI page allows non-admin users, with the proper permissions, to view submissions activity over a given time period.
Search your submissions using form/flow data! Create search filters based on a wide variety of criteria. You can even create a logical expression to specify conditions that you want to use when searching submissions.
Tenant admins can monitor submission activity using the frevvo Reports.
