Semi-persistent storage for widget state

I am now storing the widget state in the SAMPLER register, with these two functions (and not setting it to false on boot):

function getAlertsStoredState() {
    var addr = 0x40012508;
    var val = peek8(addr);
    val = val & 1;
    return val == 1;
  }
  
  function setAlertsStoredState( state ) {
    var addr = 0x40012508;
    var val = peek8(addr) & 254;
    if( state == true )
    {
      val = val + 1;
    }
    poke8(addr,val);
  }

So far it looks like it works the way I intended.
I would be interested to know if there is a way to make some code run only on first boot, but not on bnt3 long presses, but otherwise it works as expected.

Thanks for all the advice and replies.
