Cookie Policy.
We keep cookies to a minimum: the ones this site needs to work, plus optional Google Analytics that only runs if you agree.
What cookies are
Cookies are small text files a website stores on your device. We use them sparingly — only to keep the site working and, with your permission, to understand how it is used so we can improve it. We do not use cookies for advertising, and we do not share your browsing with social-media or ad networks.
Essential cookies (always on)
These are needed for the site to function, so they do not require consent. They do not track you across other websites.
- bhc_consent — remembers whether you accepted or rejected analytics, so we do not ask again on every visit. First-party, lasts about six months.
Analytics cookies (only if you accept)
If you choose Accept analytics, we load Google Analytics 4 (provided by Google LLC) to see how visitors use the site — which pages are viewed, general device type and approximate region — so we can make it better. Your IP address is anonymised, and this data is not used to identify you personally.
- _ga and _ga_<id> — distinguish visitors and measure usage. Set by Google, last up to two years.
These cookies are not set unless you accept. If you accept and later change your mind, rejecting analytics stops Google Analytics and clears these cookies.
Managing your choice
When you first visit, a banner lets you accept or reject analytics — rejecting is as easy as accepting, and nothing non-essential loads until you decide. You can change your choice at any time:
You can also control or delete cookies through your browser settings, and you can install Google's Analytics opt-out browser add-on. For how Google handles data, see the Google Privacy Policy.
Changes to this policy
If we add or change the cookies we use, we will update this page and, where required, ask for your consent again. Last reviewed: 3 July 2026.
