A cookie is a small text file a website asks your browser to keep so that it, or a third party loaded by it, can recognise you on later visits. "Similar technologies" — local storage, web beacons, fingerprinting signals — work in different ways but for the same purposes. This page covers all of them, even though we only mention "cookies" for short.
This policy is part of the wider Privacy Policy. Read both together if you want a full picture of what data this site handles.
None beyond the basic functioning your browser needs to render a page. The site does not have logins, shopping carts, or other features that would require essential cookies of its own.
We use Google Analytics 4 to count visits and measure engagement. The analytics product sets cookies in the _ga family. IP anonymisation is enabled and the analytics product's own advertising features are disabled.
| Cookie | Purpose | Typical lifetime |
|---|---|---|
_ga | Distinguishes unique visitors. | Up to 2 years |
_ga_<id> | Stores session state for GA4. | Up to 2 years |
This site is enrolled in, or being reviewed for, Google AdSense. When AdSense is active, Google and its partners may set cookies to deliver and measure ads. The exact cookies depend on which AdSense features are running and on your consent choices, but commonly include:
| Cookie | Set by | Purpose |
|---|---|---|
__gads / __gpi | Frequency capping, ad measurement, fraud prevention. | |
NID / IDE | Google / DoubleClick | Ad personalisation and measurement across Google services. |
| DART cookie | Used by Google to serve ads based on visits to this site and other sites on the internet. |
For the full and current list of cookies and identifiers Google uses for advertising, see Google's advertising technologies page and ads cookies overview.
The site loads fonts, chart and map libraries from public CDNs (Google Fonts, jsDelivr, unpkg) and map tiles from OpenStreetMap and CARTO. These services may set their own technical cookies on their domains. We do not control them; their use is governed by their own policies.
Where local law requires it — in the European Economic Area, the United Kingdom and similar jurisdictions — you will see a consent message before non-essential cookies are set. You can change your choice at any time from the "Manage cookies" link in the footer of the consent message, or by clearing cookies in your browser, which will trigger the message again on your next visit.
All modern browsers let you block, allow or delete cookies on a per-site or global basis, and offer a "private" or "incognito" mode that clears cookies when you close the window. Browsers also support the Global Privacy Control signal, which we honour where applicable.
Note that opting out reduces personalisation; it does not stop ads from being shown, and it does not stop technical cookies that the ad system uses for fraud prevention and frequency capping.
The official Google Analytics opt-out browser add-on stops Google Analytics from receiving any data from your browser, on any site that uses it.
