Does deviantART own my art?
No. At no time do you lose ownership of your original work by submitting it to deviantART.
The Submission Agreement
explicitly states that you, as the original artist, retain any and all rights appropriate to your artwork at all times. By agreeing to the Submission Agreement what you are really doing is granting deviantART the basic permissions we need in order to display, showcase, promote and otherwise make your artwork available to viewers using the wide range of different devices and services which are capable of connecting to the Internet.
