Any way to get back information in a deleted app

App deletion removes all associated data from the device - whereas App offloading only removes the App whilst leaving its data intact.

If you have an iCloud or iTunes backup created or last updated prior to deletion of the App - yes, it is possible to recover the data. It is necessary to restore the backup to your iPad:

You cannot selectively restore elements from the backup; the restore process returns your device to its state when the backup was last updated.

If you don’t have a pre-existing backup, or unless your data is also stored elsewhere, your data will have been irretrievably lost.

Unless you had made a backup of the data to iCloud backup, iTunes on older Mac or a Windows PC or to rhe Finder app on a newer Mac or to places, like Google Drive or Amazon Cloud services, DropBox, BOX and such? No.

Sorry, the data is permanently gone.
