As mentioned, this tool is meant mostly as a source of inspiration, but the images can be used for non-commercial projects as well, as long as it isn't another coat of arms creator or other similar piece of work that uses the individual images. However, I cannot allow you to use the images for commercial projects without my permission, but feel free to contact me if you do want to use it commercially, we can probably work something out.
At the end of the day this site, which I put a lot of time into, is still a means to create an income for myself, so I do have to protect some assets.
