Google Analytics is the most prevalent tracker in the world. During our last crawl, we found it on 64.2% of web sites:
Developers: every time you add Google Analytics to a site, you are helping build the global panopticon. Stop it!
@aral confirmed by HTTPArchive Data, as the most proeminent analytics script. https://www.google-analytics.com/analytics.js represents 0.64% of all the requests of their dataset. https://almanac.httparchive.org/en/2019/third-parties
I'd classify Google's font CDN as a tracker also.
* Your IP
* Your user agent
* Date & time of visit
* HTTP Referrer (knows what site you visit)
There's little stopping them from correlating your IP with your Google account, if you used the account from your IP and agreed to their services.
Oh, there's also their DNS server.

Decentraleyes barely blocks anything. It seems to work for handpicked resources instead of caching everything on third-party domains.
A user even complains here about fonts and CDNs: https://git.synz.io/Synzvato/decentraleyes/-/issues/34
With uBlock Origin, by default, I block everything except the main server. This breaks many sites, but I can live with that and manage it.
Also, I get rapidly informed of sites that prioritize saving a fraction of bandwidth and/or style over my privacy.
