How do I show confirmation only on first open?

I only want to show at first opening this sprite with an infamous, where there is information of privacy policies and terms of use. If the user clicks "aceitar" he will not see the next opening.

what I already did:

layoult start checks if array.at (4,0) = 0

      if yes displays privacy policies

if array.at (4.0) = 1

     if not it does not display privacy policies

if you click "aceitar" set the value of array.at (4,0) to 1

but this does not seem to work apparently checking array information happens even before the array loads.

Does anyone have any other suggestions for making a confirmation request.

You can store that value into the Local Storage.

Then you check that value when starting.
