A note on our app licence terms (EULA)

We do not publish our own custom end user licence agreement. For Kanban+ 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.
