This is a personal blog. It needs no account and collects nothing about its visitors beyond what is described here.
The server logs the usual technical data of every request (address, page, time, browser) so that it works and errors can be found; it is not tied to a person and is deleted after a short while. A post's view count is kept as a number, without who read it.
Cookies: one for the chosen theme (light/dark), once you change it. The blog's administrator has a session cookie. The blog itself sets no tracking cookies.
Ads: the post pages may show ads from Google AdSense. Google and its partners may use cookies and similar technologies to show ads based on earlier visits to this and other sites. In the European Economic Area consent is asked first through Google's message; without it, non-personalised ads are shown. More: policies.google.com/technologies/ads.
YouTube videos are embedded from youtube-nocookie.com and load only when you press play; until then nothing is sent to YouTube.
Reposts quote a short excerpt of the source and always link to it. Questions about this page: through the About page.
