Cookies

What cookies are

Cookies are small text files that a website places on your device (computer, smartphone or tablet) when you visit. They serve to remember your settings, to analyse how the site is used, or to improve your experience. Besides cookies, a website may use other browser storage techniques — such as local storage (localStorage) — which serve a similar purpose but are technically not cookies. Cookies cannot access other data on your device and, on their own, contain no information that directly identifies you.

The current state

On an ordinary visit this website sets no analytics and no advertising cookies, for any visitor, wherever you are. Visits are measured with Google Analytics 4, and that measurement runs without cookies: Google stores no identifier on your device, so it does not recognise you across visits or pages. Opening a page does make one request to a Google server to load that tag. There is one exception to what is written to your device, described below rather than passed over in silence. No advertising network is integrated.

In short: on an ordinary visit no cookie is set. Google Analytics 4 measures visits without cookies, with Google’s consent setting held at "denied" permanently, because this site carries no mechanism that could change it. The one exception is the gr_int internal-visit flag, described below, and it is written only if you ask for it. If the set of services changes — for example once advertising is added — this page will name each cookie and explain how consent is given, managed or withdrawn, the same way for every visitor, regardless of where they are.

Technically necessary storage

So that the site can respect a choice you make, a small amount of information may be stored in your browser’s local storage. It is technically necessary, serves only to make the site work, and is stored regardless of any consent. This is local storage (localStorage), and so technically not a cookie:

• Your language-suggestion choice — when the site notices your browser prefers the other available language and you dismiss that suggestion, this remembers your choice so the suggestion does not reappear on every page.
• The gr_int flag — but only if you deliberately open a page with ?internal=1 appended. On an ordinary visit nothing is written. What it is and what it does is set out below, under “Excluding our own visits”.

This entry remains until you clear your browser’s storage. It contains no name, no email address and no identifier that could be used to build a user profile.

Google Analytics 4 — measurement without cookies

Visits are measured with Google Analytics 4. Google Consent Mode v2 holds every storage signal at "denied" the same for every visitor, in every country, and this site carries no consent message or other mechanism that could change it — so the tag runs cookieless, permanently. Each measurement message carries the page address, where the visit came from, the IP address (from which Google derives an approximate location) and general device and browser characteristics, with no cookie and no identifier that recognises you across visits or pages. That data may be processed outside the Netherlands.

We publish no cookie list for analytics because there is no analytics cookie to list. If advertising is ever added, a full overview will be published here first — with the name, provider, purpose and storage duration of each individual cookie.

Excluding our own visits

One exception, named here rather than passed over in silence: on every page view the measurement code checks whether the gr_int flag is present in your browser. That is our own exclusion for internal visits, so that our test traffic does not end up in the figures. It is written only when a page is opened with ?internal=1 appended — as a cookie with a lifetime of one year, and additionally in local storage. Without that, nothing is written, and nothing on this site links to it. It holds a single flag and nothing about you: no name, no email address and no identifier that could be used to build a user profile. You delete it by clearing this site’s data in your browser.

Third-party cookies

Analytics and advertising cookies would be third-party cookies: after launch they would be set by Google LLC (USA) via the Google Analytics 4 and Google AdSense services. Google LLC is certified under the EU–US Data Privacy Framework, through which the European Commission has found an adequate level of data protection for certified companies. Google Analytics 4 truncates IP addresses; the advertising network may, as a third party, process further data for advertising purposes (including the IP address and device identifiers). How Google uses data and how you set or switch off personalised advertising can be found at policies.google.com/technologies/partner-sites and adssettings.google.com. No such third-party cookie is set on this site today.

Managing and withdrawing your consent

There is no consent message on this site, because no cookie requiring consent is set. The button below stands ready for the moment advertising does run:

Change your cookie consent

Independently of all this, you can delete cookies at any time through your browser settings, or block them from being set in the first place:

• Chrome: Settings → Privacy and security → Cookies
• Firefox: Settings → Privacy & Security → Cookies and Site Data
• Safari: Settings → Privacy → Manage Website Data
• Edge: Settings → Cookies and site permissions → Cookies

Deleting cookies does not impair your use of this website.

Relationship to data protection

This cookie policy supplements our privacy policy, which describes what data we process, how, and what rights you have. The website sets no analytics or advertising cookie.
