"Our framework stores Google Fonts locally. When you select a Google font in the Style Customizer, the font files are downloaded to your web server and are included into the CSS. This means the font is loaded from your own server, and no requests to the Google Fonts server are sent. This not only helps with GDPR-compliance, but it also improves your Google PageSpeed rank."
Not possible at Joomlart? This is also a Joomla template and builder provider.
A most welcome feature imo.
