The danieldunderfelt.com website uses the Fathom web analytics service, which I self-host on my own server using the domain
stats.verycool.tech. Fathom is open source and can be viewed on Github: github.com/usefathom/fathom. Fathom collects minimal data on how many pageviews danieldunderfelt.com gets, which pages are visited and from which referrer the visitor came.
The danieldunderfelt.com website sets one cookie, the Fathom cookie. The cookie contains a random identifier and does not track the user around the web. Fathom tracking can be easily disabled by enabling "do not track" in your browser. From Fathom's data policy:
Fathom gathers a minimal amount of data to identify specific information about a website’s use. For example, which pages have been visited and for long they were viewed.
Fathom does not process an excessive amount of data about each website user to achieve this. Unlike many other analytics services, Fathom does not gather data points such as IP address, device configuration, geo-location data.
Fathom does not store a unique identifier for each website visitor so we can track their path through the website. We regenerate a new identifier for each visitor every time they visit a page. We do not link the old identifier to the new one.
We forget about a site visitor once they have not interacted with the site after 30 minutes.
