§ 1Overview
When you visit this site, your browser may store small pieces of data — cookies — to help the site function correctly. We use them sparingly, and only for two purposes: to remember a preference you have set, such as your language choice, and to support a privacy-preserving form of analytics that helps us understand which pages are read and how the site is performing.
We do not use cookies to identify you personally, to follow you across the web, to build a behavioural profile, or to share data with advertisers.
§ 2What this site stores
Cookies are commonly grouped into four categories. The table below sets out how each category applies — or does not apply — on this site.
| Category | What it covers | On this site |
|---|---|---|
| Strictly necessary | Cookies required for the site's basic operation — security, navigation, accessibility. | None set |
| Functional | Cookies that remember a preference you have set, such as language or display options. | Language preference |
| Analytics | Cookies that help us understand site usage in aggregate. | Cookieless |
| Marketing | Cookies set to deliver advertising or build behavioural profiles. | None |
In practice the site currently sets a single functional cookie that remembers your chosen language, so you do not have to re-select it on every visit. Nothing in the strictly necessary, analytics, or marketing categories is set.
§ 3A note on analytics
We measure how the site is used so that we can improve it — which Insights pages are read, where readers come from, which devices are common. The measurement tool we use is configured to be cookieless and to record only aggregate data. It does not set tracking cookies, does not use browser fingerprinting, and does not share data with advertising platforms.
In practical terms: we see that a page was viewed, not who viewed it. No identifier for you is stored in your browser by the analytics tool.
§ 4Embedded content
Where our pages embed content from elsewhere — for example, an interactive map drawn from open data, or a third-party document viewer — the third party concerned may set its own cookies according to its own policy. We try to keep such embeds to a minimum, and to prefer sources that do not require tracking cookies to function.
§ 5Managing your preferences
You can review your preferences for the categories above at any time, or withdraw any consent you have given, by opening the preference panel below.
You can also disable or delete cookies directly in your browser. Browser-level controls override anything we display here. If you disable functional cookies, some preferences — such as your language choice — may not be remembered between visits.
§ 6Changes to this notice
If we change how we use cookies, this page will be updated to reflect the change. The most recent version of the notice is always the version visible here.
