Copyrights: using HiHaHo on someone else’s video
In most cases, it is completely legal to use HiHaHo on a public video. This is because HiHaHo does not alter the original video, it only creates an interactive layer. For this reason, most copyright laws do not apply.
Since this is a difficult and complicated matter, we’ve collected more information on copyright infringement laws here. You yourself are in charge of using public content with respect. Please do read our terms of service and our disclaimer, too.
