Saving Data Locally

I have an offline presentation for a client that needs to have a form submitted data saved local on the machine (kiosk) to be gathered later.

I researched on google and found fscommand to write to a txt file but this no longer works and is sorta sloppy. I don’t have the expertise to run a local db and write to it.

Can anyone recommend a solution for this? 3rd party app?

Id be insanely greatfull.
