Google Fonts is a font embedding service library. Google Fonts are stored on Google's CDN. The Google Fonts API is designed to limit the collection, storage, and use of end-user data to only what is needed to serve fonts efficiently. Use of Google Fonts API is unauthenticated. No cookies are sent by website visitors to the Google Fonts API. Requests to the Google Fonts API are made to resource-specific domains, such as fonts.googleapis.com or fonts.gstatic.com. This means your font requests are separate from and don't contain any credentials you send to google.com while using other Google services that are authenticated, such as Gmail.
