Do so ó ->
You can take this example here: link , translate to the language (s) s) that you have implemented in the application and put everything into a .html file and publish that file to your domain.
Once you have done this, go to the developer console under "application details" below, there is "Privacy Policy", in the "url" field you will be able to url pointing to the file you created in the next step, something like : link .
In my case, I have several apps, all of them in more than one language, so I created the page in php and I pass the app through the url and show it according to the name entered in the url, type link , even though for me, in all apps, my privacy policy is generic.
I also implemented a jquery mechanism on the page that I created to open in the face language.
That's it.
