We store no personal data and run no third-party advertising networks or social-media trackers. The systeme.io links on some pages are simple affiliate links, not tracking ads. The only analytics is Google Analytics, described below. Pages are static; your option choices (paper size, colors, title) stay in your browser's localStorage and are never sent anywhere.
I use Google Analytics (GA4) to see which pages people use, so I can keep making this site better. Google's analytics sets a cookie called _ga in your browser and collects a few basics: the pages you view, your approximate region, the site that sent you here, and your device or browser. I read only the aggregate numbers, not individual people. This site deliberately shows no cookie banner, so nothing pops up over your calendar. If you would rather not be counted, you can block googletagmanager.com in your browser, use a content blocker, or install Google's official opt-out browser add-on (https://tools.google.com/dlpage/gaoptout).
