This site sets no cookies. Not a reduced set, not essential ones only: none at all. What follows is the complete inventory of everything stored in your browser and everything loaded from elsewhere.
Stored in your browser
One entry, in localStorage, under the key sw_consent_v1.
It holds the choice you made in the consent banner, the time you made it, the version of this inventory it applies to, and the regional default you were shown. It stays on your device, it is never transmitted, and it exists so that we do not ask you the same question on every page.
Clearing site data in your browser removes it, and the banner will then ask again. The link in the footer lets you change the decision without clearing anything.
Loaded from another server
One thing, and only on pages carrying the contact form: Cloudflare Turnstile, which checks that a submission comes from a person rather than a script.
Turnstile is cookieless by design and does not track you between sites. It receives your IP address and limited technical signals from your browser in order to run the check. It loads as security infrastructure rather than as a tracker, which is why it is not behind the consent banner.
Nothing else. Fonts are served from this domain rather than from a font provider. The explainer videos play from this domain rather than from a video platform, so no platform learns that you watched one. There are no advertising pixels and no embedded third-party widgets.
Analytics
None is running. No analytics software is loaded on this site at present.
The consent banner already offers analytics and marketing categories, and both default to declined. They are there because the machinery has to exist before the tag does, not because something is quietly active. If analytics is ever switched on, it will appear on this page and the inventory version will change, which makes every stored decision count as no decision so that you are asked again rather than inheriting an answer you gave about a different site.
Server logs
Requests produce technical log data at the edge: a shortened IP address, the time, the page, the referrer, and the browser and operating system your device reports. That is needed to serve the page and to defend against attacks, it is not stored in your browser, and it is described in full in the privacy notice.
