Google web fonts are transferred to the cache of your browser to prevent multiple loading. If the browser does not support Google Webfonts or prohibits access, contents will be displayed in a standard font. The view of script libraries or font libraries automatically triggers a connection to the operator of the library. Theoretically it is possible - but currently also unclear whether and if so for what purposes - that operators of such libraries collect data.
