Not written yet. This page says so rather than pretending otherwise.
The HEXR developer agreement and content policy are pending legal review.
No terms exist yet. Nothing on this site constitutes an agreement, a licence, or a promise about how a published mini-app will be treated, and no page here should be read as one.
We would rather leave this page empty and say why than publish placeholder terms that look real. When the documents have been reviewed, they will appear here and you will be asked to accept them explicitly.
There is nothing else on this page on purpose. It links nowhere but back to the rest of the developer documentation.
