I'm working on a little Quiz App. To get questions I use Open Trivia DB
All data provided by the API is available under the Creative Commons Attribution-ShareAlike 4.0 International License.
I have read a little bit about the license but I'm not sure if my app is an adaption of the work and therefor I have to publish it under CC-BY-SA 4 as well.
The app queries a question from the database, shows it to the user, and lets him chose an answer. It doesn't modify the question.
According to an answer to this question.
You are not required to provide a download link for your modified emojis. For license compliance, it is enough that you don't forbid further modification if someone has scraped your modified emoji from your application.
Does this mean if I have to make the app CC-BY-SA, I don't need to publish the source, and if so, how do I mark the app as CC-BY-SA in this case?
