Some people eat higher on exercise days. But some others find the day after exercise is a hungry day rather than the day of exercise. Yet others find it doesn't really matter.
As long as your entire weekly calories burned is roughly the same as your goal calories burned, you are fine to eat anywhere in your range that you feel comfortable to every single day, regardless of exercise that particular day or not.
And if your weekly calories burned doesn't match your goal - just change the goal. :)
