A normal pizza dough should have a tiny tiny amount of sugar - 2 grammes per pizza maybe, just enough to feed the yeast. It’s usually all flour and water with only tiny bits of sugar, salt and olive oil...

Same goes for the pomodoro - it’s not ketchup, for dog’s sake, it should be just tomato, garlic, herbs (and onions and olive oil maybe). If your pizzeria puts heaps of sugar into the pomodoro, you might want to consider switching.
