Licences and credits

Quizotic stands on other people’s work. This page lists every icon, emoji, flag, illustration, photo and typeface we did not draw ourselves, who made it, and the licence we use it under. We only ship work whose licence lets a quiz maker offer it to its users; where a creator asks for a notice or a credit, it is kept here and beside the files.

Visual library

The icons, emoji, flags, illustrations and shapes you can add to a quiz or presentation. Using one costs no upload.
