Hello!
It is not open source, but not for any conscious reason. Throughout the almost 20 years I worked as a programmer, it was always on private projects. I suppose that's where the habit stuck with me. However, I love the philosophy of Open-Source, so if the project gets approved, I will consider the task of organizing it with the intention of making it public.
Good point!
