You can store the sauce in the fridge for up to 5 days. Put it into an airtight container and place it in the fridge.  To freeze, allow the sauce to cool to room temperature. Add the sauce into a freezer-safe airtight container. Seal it well, label and date it. Place into the freezer; it will stay good for about 3-4 months. It is common for the sauce not to look the same as when you made it, but it should taste the same and be safe to eat.
