Apps, sheets and stories can be published. Access rights control which users are allowed to publish different kinds of content.
Publishing apps
When you publish an app, the sheets and stories of the app will become available to the other users that have access to the stream that your published app belongs to.
When your app is published, it will be locked. This means that you will not be able to edit your published sheets and stories, but you can use them to analyze your data.
If you want to continue working on the app, you can do so in your private copy of the published app, and eventually replace the published app, if needed.
No one can edit the sheets and stories that were published with the app, but if you have the correct access rights, you can add private sheets to a published app. When an app is published, only the master items and charts will be available, in the library panel, when editing your private sheets. You cannot edit a story of a published app.
Apps are published from the Qlik Management Console.
Publishing sheets and stories
The private sheets and stories that you create as a part of a published app can also be published, to be made available to the other users of the published app.
