I am building a simple website and therefore wanted to avoid worrying about GDPR compliance by simply not processing or tracking any user data.
However, when investigating my only third-party service "Font Awesome" I noticed that they track the amount of monthly page views of my page (they even openly display it in my account dashboard) and potentially which icons are used. Note that they claim that their service is GDPR-compliant. References for all statements here.
Is this form of tracking allowed under GDPR without prior consent, as it can not be considered required for the functionality of the site? Furthermore, if this is considered illegal under GDPR, who will be responsible, I (the site owner) or Font Awesome (responsible for the tracking)?
If possible please provide sources for the main statements of your answer.
Thank you.
