Your content
The units, terms and files you create stay yours. By adding them you let MeraLearn store them and show them to your students so the games can run.
A unit is private unless you share it. When you share a unit with another teacher, give them its link, or make it public in the library, you let those teachers see it and copy it into their own units, where they can change it and use it with their students. Their copy credits you as its author and stays theirs, even if you later stop sharing or delete yours. Your students and their results are never shared.
Share only what you made or have the right to share. MeraLearn can hide a shared unit that is reported, or that breaks these terms.
