Privacy

What this site collects, why, and how to avoid it. Short version: no accounts, no advertising, no data sold — but one third-party tool records how pages are used, and that is worth knowing about.

Microsoft Clarity

This site uses Microsoft Clarity to understand how pages are read — which charts people interact with, where they stop scrolling, and what breaks. Clarity is loaded only on the published site, never in local development.

Clarity does more than count visits. It records session replays and builds heatmaps, which means your interactions with the page — scrolling, clicks, mouse movement — are captured and replayed. It sets cookies (_clck and _clsk) to recognise a returning browser, and it collects your IP address, browser, device and referring page. Microsoft masks text content by default, and this site does not ask for or transmit any personal information of its own.

The data is processed by Microsoft under their own privacy terms. See Microsoft's privacy statement and the Clarity terms of use for what they do with it.

How to opt out

Clarity respects the browser's Do Not Track and Global Privacy Control signals where they are sent. Any content blocker or tracker-blocking browser will also stop it loading, and nothing on this site depends on it — every page works fully with Clarity blocked.

What this site itself stores

One item in your browser's local storage, holding your language choice so the site opens in the same language next time. It never leaves your browser. There is no account system, no newsletter, no comment system and no advertising.

Hosting

The site is static files served by GitHub Pages, which keeps its own server logs including IP addresses. That is outside this site's control and covered by GitHub's privacy statement.
