I've been using qlik for about a week and have all my dashboards up but I do not want viewers to export the data from the charts after I publish the apps. Is there a method to prevent viewers from exporting data with a right-click?
Not that I know of. I'd say right your own extensions with export disabled but your positing in cloud so extensions aren't an option for you. The thing is if you let people see your data if they want it they will have it if you make it hard or easy for them e.g. Take screen shots, screen scrap etc... I'd probably notworry about it.
Not in Qlik Sense at the moment. If you use the other product QlikView you have the ability to uncheck export data if that is a really important requirement.
Qlik Sense Server is an environment which encourages other users to have controlled access to the underlying data model e.g. through master items etc... and use it to create their own visualisations if they have the right skills and permissions.
If you need to tie it down QlikView has move developer configuration tools to do this.
