What I collect

I measure how people use this site with three tools: Vercel Web Analytics, Google Analytics 4, and a small tracker I built myself that stores its data in my own database. What they receive depends on the choice you make in the cookie banner.

If you decline (or haven't chosen yet)

Vercel Web Analytics and my own tracker run. My tracker records anonymous page views: the page, where you came from, any campaign tags in the link, your screen and window size, language, time zone, and your browser, operating system and device type. It also records clicks on the footer links, opening the contact form, and sending it (never what you wrote), plus how long the page was open and how far you scrolled. I also record your approximate location (country, region and city), which Vercel works out from your connection. Google Analytics is not loaded.

None of this includes your IP address, and nothing identifying you is saved in your browser, so I can't tell whether two page views came from the same person.

If you accept

Everything above, plus: a random visitor ID (kept in your browser's local storage for up to a year) and a session ID (which expires after 30 minutes of inactivity), so I can count returning visitors and visits. I also store your IP address. Google Analytics 4 is loaded and collects its own data under Google's terms.

How long I keep it

After 90 days, stored IP addresses are shortened automatically (the last part of an IPv4 address is dropped, and an IPv6 address is cut to its first 48 bits), so they no longer point to a single connection. The rest of the data is kept indefinitely.

The contact form

What you type in the contact form is sent to Formspree so it reaches me. It is never part of my analytics, and none of the three tools above receive it.

Your choice

You can change your choice at any time, and it takes effect straight away on the page you're on. If you decline, Google Analytics stops sending data and my tracker stops sending your visitor and session IDs. Cookies Google already set stay in your browser until you clear them.
