Privacy

This site keeps its own simple visit log and also uses Google Analytics to see how visitors find it. Every advertising feature is off: nothing is used for ads, and there are no ad trackers. Apart from Google Analytics, everything on the page, fonts included, is served from this site.

The site's own visit log

For each page view: the page, the referring site (domain only), a rough visitor type (person, search engine, AI crawler or other bot), the country reported by Cloudflare, and a visitor code. The visitor code is a hash of your IP address and browser with a salt that changes every day, so it can't be turned back into your IP address and visits can't be linked across days. The IP address itself is never stored.

Clicks on the email, phone, LinkedIn and resume links are counted the same way.

Google Analytics

Google Analytics records the pages you view, how you arrived (a search, a link or directly), your approximate location and device type, clicks on the email, phone, LinkedIn and resume links, and the fact that a contact message was sent (never what it says or who sent it). Google signals, ad personalization and advertising data sharing are off, and Google Analytics does not store IP addresses. It keeps this data for 14 months.

In the EEA, the UK and Switzerland, and in any browser that sends a Global Privacy Control signal, Google Analytics runs without cookies. Elsewhere it sets two first-party cookies (_ga and _ga_GJL77XSGKH) that hold a random visitor ID, so repeat visits can be counted. Any content blocker, or Google's opt-out browser add-on, stops it.

Cookies

  • If you switch between light and dark mode, that choice is stored in a cookie so the site can show it on your next visit.
  • If you arrive through a personal link I sent you (a /r/… address), a session cookie remembers that link until you close your browser, so I can see that it was used. It holds only the link's code.
  • The Google Analytics cookies described above, only outside the EEA, the UK and Switzerland and only without Global Privacy Control.

Messages

Messages sent through the contact form are stored so I can reply. They are not shared with anyone.

Retention and questions

The site's own visit log is deleted after 180 days; Google Analytics keeps its data for 14 months. The site is served through Cloudflare, which processes requests to deliver and protect it. Questions: michael@michael-kuhlman.com.
