Which license the boxlogic follows?

I'm a programmer of Hiswill Co., Ltd.

My company is a printing factory and wants to minimize delivery cost
by developing a 3d-bin packer program with multiple type of wrappers.

I've adopted your open-source "Boxologic" for 3d-bin packing and
I've implemented the "multiple type of wrappers" with genetic algorithm.

The program's outline is almost developed, however,
license of the Boxologic is not specified in your GitHub repository.

Which license the Boxologic follows?
Do I need to open my code to be public or there's something to fee?
