What cookies are

Cookies are small files a website stores on your device. Some are essential to make a site work. Others are optional, such as analytics cookies (to see how a site is used) and marketing cookies (to measure and improve advertising), and can only be used if you agree.

The cookies we use

Essential cookies

These make the site work, so they’re always on.

Cookie	What it does	How long
Your cookie choice sits_consent	Remembers whether you accepted or rejected optional cookies.	6 months
Website login wordpress_*	Keeps the people who manage this website logged in. Visitors don’t get these.	Up to 14 days

Analytics cookies (optional)

These help us see how the site is used so we can improve it. They only run if you click Accept all on our cookie banner, and never identify you to us.

Cookie	What it does	How long
Google Analytics _ga, _ga_*	Counts visits, which pages are viewed and how people found us. Google keeps the statistics for 14 months.	Up to 2 years
Microsoft Clarity _clck, _clsk, MUID and others	Shows where people click and scroll, with heatmaps and recordings of how pages are used. Anything typed into our contact form is hidden. Microsoft keeps recordings for 30 days and heatmaps for 9 months.	1 day to 13 months

Marketing cookies (optional)

We don’t use any at the moment. If we start, we’ll list them here and ask for your consent first.

The website doesn’t load anything else from other companies, such as fonts, maps or videos, so no other cookies are set.

Changing your choice

You can change your choice at any time with the Cookie settings link at the bottom of every page. If you reject cookies you’d accepted before, we stop the analytics and remove the analytics cookies set on our website. Cookies Microsoft set on its own addresses (clarity.ms and bing.com) can only be deleted in your browser settings, where you can also block or delete any cookies.

Changes to this policy

We’ll update this page whenever the cookies we use change, and change the date at the top. If we add a new kind of optional cookie, we’ll ask for your choice again.
