Do it this way ->
you can take this example here: https://media.termsfeed.com/pdf/privacy-policy-template.pdf, translate to the language(s) you implemented in the application and put it all in a file . html and publish that file in your domain.
Once that’s done, go to the Windows console in "app details", right below, there’s "Privacy Policy", in the "url" field: http://seudominio.com/apps/suaprivacypolicy.html.
In my case, I have several apps, all of them in more than one language, so I created the php page and pass the app by the url and show as the name given in the url, type http...myprivpol.php? app=App I want to shutdown", even because for me, in all apps, my policy is Renewable.
I also implemented a jquery engine on the page I created to open in the language of the guy.
that’s it.
