Why does TubeBuddy need access to to websites and why does it say "TubeBuddy can delete my videos"?? We know - it sounds scary. But these are required in order for our product to work. For example, we need access to YouTube and Twitter and Facebook in order to show you how many times a video has been shared. We need access to YouTube in order to provide keyword research and background calls to save changes. Please note that we NEVER perform any action that you don't specifically request us to do.
