Ask HN: Static Site Analytics Without Cookies?

I run a couple of static sites, and am interested in aggregate stats about visitors - total number, referrer/origin, time of day and maybe location at the resolution of like, 100Km or so (eg State of origin or similar).

Are there any easy ways to do this that don't need a cookie consent pop-up, and are GDPR compliant (by recording zero PII)?

I'm happy to trade recording much less information about users in order to achieve this.
