How to fix cracks from shifting house?

I have two cracks that shrink and widen respectively depending on the season. The cause seems to be that my house shifts depending on the weather. While I’ve been told that the settling is normal and doesn’t need to be repaired, the cracks themselves are unsightly. However, if I repair them, it seems like they will just reappear.

What are my options?

Typically, horizontal cracks are ok, fix vertical cracks when you can afford it.
