A note on licence terms for our Marketplace apps (EULA)
We do not publish a custom end user licence agreement for Kanban+ or OnTask. For both apps, on the Atlassian Marketplace, we have elected the Bonterms Standard End User Agreement, a widely used, plain-language industry-standard agreement that the listings call the Standard Agreement, with a short set of app-specific additions shown there as our Provider-Specific Terms. You can read both on each app's Marketplace listing. Diagon has its own EULA, linked above.
