The developer of Dragon Shout, a free utility for players of The Elder Scrolls V: Skyrim, has been told by ZeniMax that he is infringing copyright.
The Bethesda owner has not yet demanded that the app be removed, but has issued a warning notice highlighting its concerns, TouchArcade reports.
"I did my best to ensure the app was not violating anything," creator Blalock explained. "I looked up US trademarks and copyrights for 'Dragon Shout' and at the time there wasn't any.
“I had the map hand drawn. I intentionally didn't use any graphics or wording that would possibly be owned by Bethesda. So, I'm still not sure what they say the app violates."
Dragon Shout remains available on the Apple App Store and, for the time being, is free to download.
