What I measure
I use PostHog (opens in a new tab), hosted in the EU. It records the pages you open, the site you came from, how long you stay, how far you scroll, the links and buttons you click, and your browser and device type.
What I don't store
PostHog sets no cookies and stores nothing in your browser. It briefly uses your IP address and browser details to create a temporary visitor ID, so one visit counts as one visit, and then discards the IP address. I can't see who you are, and I don't record your screen.
Hosting
Vercel (opens in a new tab) hosts this site. Like any host, it handles technical data such as your IP address to deliver the pages.
Your theme choice
If you switch between light and dark, your browser saves that choice in local storage. It stays on your device.
