>> The site says it’s CC0. > Not sure that works everywhere. IANAL, so I can't say it works "everywhere", but CC0 was created to give up as many restrictions in as many jurisdictions as possible: > CC0 helps solve this problem by giving creators a way to waive all their copyright and related rights in their works to the fullest extent allowed by law. CC0 is a universal instrument that is not adapted to the laws of any particular legal jurisdiction, similar to many open source software licenses. And while no tool, not even CC0, can guarantee a complete relinquishment of all copyright and database rights in every jurisdiction, we believe it provides the best and most complete alternative for contributing a work to the public domain given the many complex and diverse copyright and database systems around the world. * https://creativecommons.org/share-your-work/public-domain/cc0/ https://creativecommons.org/share-your-work/public-domain/cc... If you are concerned about a particular jurisdiction, CC has national chapters that perhaps have more localized information: * https://network.creativecommons.org/chapter/ https://network.creativecommons.org/chapter/
