Web Page Translation in Safari on Mac
Safari analyses each web page you visit to determine its language. This determination is made entirely on your device. If the web page can be translated to any of your preferred languages, you can choose to translate it. If you translate, Safari will send the web page’s contents (including the full text) to Apple’s servers for translation. After the translation is complete, Apple will discard the contents of the web page.
Note: The availability of translations and the number of languages that can be translated may vary by country or region.
If the web page was not viewed in Private Browsing mode, then Safari will also send the web page’s address to Apple. Apple will store the address for up to 5 years to improve Apple’s products, services and technologies. Since Apple does not store the contents of web pages you translate, only publicly accessible web pages will be used to improve Apple’s products, services and technologies.
Web page contents and addresses sent to Apple are not associated with your Apple ID, email address or other data Apple may have from your use of other Apple services.
In order to provide you with a better browsing experience, after translating a particular web page, other web pages in the same domain that you visit within the same tab may also be translated. Safari will stop automatically translating when you visit a web page that is no longer in the same original language, or a web page on a different domain.
