Cookie notice

This notice explains the cookies and local storage used on this site, and how you can control them. Last revised: October 21, 2026.

Essential storage

Two local values are stored in your browser and are not used for tracking:

site:theme — remembers whether you chose light or dark mode. Stays until you clear site data.
site:consent — remembers your cookie choice. Stays until you clear site data.

Advertising cookies

If advertising is enabled, Google and its partners may set cookies to limit repeated ads, measure impressions, and, where you consent, personalize advertising. These cookies are set by the advertising vendor, not by this site. You can review and change your choices at Google Ads Settings and aboutads.info.

Analytics cookies

If aggregate analytics are enabled, they run only after you accept non-essential cookies. They are configured not to build cross-site profiles.

Managing cookies

Use the banner on your first visit to accept all cookies or keep essential only. You can change your mind at any time by clearing site data for this domain in your browser settings; the banner will appear again on your next visit. Blocking all cookies may affect how the theme toggle behaves.
