A note on licence terms for Kanban+ (EULA)
We do not publish a custom end user licence agreement for Kanban+. For that app, on the Atlassian Marketplace, we have elected the Bonterms Standard End User Agreement, a widely used, plain-language industry-standard agreement, with a short set of app-specific additions. You can read the elected agreement and those additions on the Kanban+ Marketplace listing. Diagon has its own EULA, linked above.
