I want to hide the back arrow

I have a tablet running your App and the form works great. However, the tablet is setup in a public space and I want to avoid someone hitting the back arrow and accessing all my forms?

Are you using the Android app and loading the form on Kiosk Mode? If yes, if the back button is an internal button (digital buttons), clicking it shouldn't go back based on my test. However, if those are physical buttons, I'm afraid that can't be prevented probably due to limits on the API.

Anyway, if you haven't tried Kiosk Mode, I would suggest to try it. Guide: https://www.jotform.com/help/571-How-to-Use-Kiosk-Mode-in-JotForm-Mobile-Forms
