Hey,
the applicable law only starts on May 25th 2018, it is called “DSGVO”(german) or “GDPR”(europe), and if i’m not mistaken and understood the things right, we are not even allowed, to use google-webfonts, based on a google url, since then the client who visits our page will also connect to google, even tho he didn’t ask for it.
most things i read where in german. But here something about the laws in english: https://www.eugdpr.org/
