How do I change how many NCarbs I plan to eat in a day

I just joined and downloaded the app.  It figured out for me how many NCarbs I should eat in a day but I am not liking the number they gave me.  I think it is way too High!  How do I change it.  I can't seem to find a profile or anywhere I can change my goals or amt of NCarbs or fat etc that I should consume in one day?

Any help would be greatly appreciated.

Thanks
