264 g of carbs per day - is that low carb ?

I am a premium member and though low carb is low carb.  My app says i can eat 264 g of carbs PER DAY.  How can i get this set to a more low carb amount ?  No idea as to how it got so out of whack ?  I am a new subscriber but if 264 g of carb per day - all i would do is eat carbs for every meal and i would still not exhaust my carbs.  I thought it is maybe per week but it changes to 264 per day when i start logging food for new day.  help
