Prevent User's Personal Data From Being Translated
A simple and definitive way to entirely avoid potential exposure of user information to the translators and potentially to the public is by turning off Public Phrase Discovery in your site's Phrase Discovery page which you can find here: "Site Manager > Details > Phrase Discovery".
You can still discover phrases on your production site, but you'll need to use our Verified Phrase Discovery feature by running the following code in your browser's console:
sitetran.toggle_phrase_discovery();
But, you should ignore or exclude elements and their contents from being translated or discovered, by adding the class "notranslate", or the attribute translate="no" to your element, or by using the SiteTran Widget init option which you can read about here.
