It may be good to start out talking about what we are purchasing when we buy a rubber stamp or a digital stamp. When we buy a rubber stamp we are purchasing a limited license for personal use of the image on the stamp. We own the rubber, we own the block or cling foam it is on, but we do not own the image. The artist or company selling the stamp retains the ownership of the image. This is just like a CD; we own the material the CD is made out of, we do not own the song. Art, such as music, images, etc are intellectual property of their originators. When we purchase a digital image we are purchasing only the limited license to use that image personally.
An Angel Policy is a form of limited license that specifies ways in which a stamped image may be used. Angel policies were developed to allow crafters additional rights in use of rubber stamps and other crafting materials that are copyright protected. Angel policies are not all-inclusive. If a company has an "angel policy" that does not mean we can do whatever we wish with their image.
What does "Angel Policy" mean then? It means exactly what it says. So if it does not mention something, for example: swapping, sharing, trading, then the angel policy does not allow that. It may say we can sell a certain number of hand-made items using their image, but that in no way implies any other use. Perhaps that company may also allow swapping or sharing of their stamped image, but we would have to contact the artist/company for permission to do so.
