Cookie policy

Last updated 2 October 2026.

A cookie is a small file a website asks your browser to store. Some are needed for the site to work at all. Others watch how the site is used. The law treats those two things differently, and so do we.

Strictly necessary cookies. These are set by Squarespace, who host this site. They keep your session alive as you move between pages, remember whether you have dismissed a banner, and protect forms against abuse. They do not identify you as a person and they cannot be turned off without breaking the site, so we do not ask permission for them. They are set the moment you arrive.

Your consent choice. Our consent tool, CookieYes, asks whether you accept the non-essential cookies described below. It stores your answer in a cookie called cookieyes-consent, so the banner does not ask you again on every page. That cookie lasts for one year. Remembering your choice is strictly necessary, so it is set whichever way you answer.

Analytics cookies. These tell us which pages get read, how people arrive and where they give up. That is useful and it is not necessary, so nothing of this kind runs unless you say yes. The three tools below are loaded through Google Tag Manager, which holds them back until you accept analytics cookies. Tag Manager itself does not set cookies.

Google Analytics counts visits, the pages read and the forms sent. It sets _ga and _ga_NCVS9WNCHJ, which last two years.

Microsoft Clarity shows us, as heatmaps and recordings, where people click, scroll and stop. Anything typed into a form is hidden from the recordings. It sets _clck, which lasts a year, and _clsk, which lasts a day. Microsoft may also set its own cookies on its own domain.

Apollo tells us which organisations visit the site, worked out from the network address a visit comes from. It works at company level only and does not identify you as a person. It does not set a cookie. Instead it keeps an anonymous identifier, apolloAnonId, in your browser storage so that repeat visits from the same browser are counted once.

Third-party cookies. We do not run advertising on this site and we do not allow advertising networks to set cookies through it. If we embed something from another service, a video for example, that service may set its own cookies once you play it. We will say so at the point it happens.

Changing your mind. You can change your choice at any time from the consent button at the bottom of every page. You can also clear or block cookies in your browser. Every major browser has a setting for it, usually under privacy or site data, and blocking everything will break parts of this site and most others.
