What a cookie is, briefly
A cookie is a small file a website asks your browser to keep and send back on later requests. Related technologies do the same job by other means: local storage keeps values in the browser, and a web beacon is a tiny invisible image whose only purpose is to be fetched, which tells the server that a page was opened. Everything below applies to all three.
Cookies Reserchers sets itself
None, for measurement. Our request log runs entirely on the server, and the Cloudflare Web Analytics beacon that measures page speed is cookieless by design — it reads timing data from the browser's performance API and stores nothing in local storage, session storage, or IndexedDB. Both are described in the privacy policy. That is why you can block every cookie on this domain and the site behaves exactly the same.
The one exception is your consent choice. If you are shown a consent banner and answer it, that answer has to be stored somewhere in your browser or you would be asked again on every page. That record is strictly necessary, contains no advertising identifier, and is the mechanism by which a refusal is honoured.
Cookies set by Google and its advertising partners
Display advertising on this site is served by Google AdSense. When an ad loads, Google and the vendors it works with may set cookies on your browser or read ones already there. We do not control these cookies, cannot read them, and never receive their contents. They are used to:
- choose which ads to show, either from the page you are reading or from your prior visits to this and other websites
- limit how many times you see the same ad
- measure whether an ad was seen and whether it led to a visit or a purchase
- detect click fraud and invalid traffic
Google names the specific cookies it uses for advertising, what each one stores, and how long each lasts on itsadvertising cookies page, and explains its wider use of publisher data inHow Google uses information from sites that use its services.
Categories, in the terms the consent banner uses
| Category | What it does | Refusable |
|---|---|---|
| Strictly necessary | Stores your consent answer so it can be honoured. | No — refusing it would mean re-asking on every page |
| Advertising | Chooses and caps ads, measures whether they were seen, and blocks fraudulent clicks. | Yes |
| Personalisation | Uses your prior browsing to pick ads rather than choosing them from the page's own subject. | Yes |
| Analytics | No cookies. The request log is server-side, and the page-speed beacon is cookieless and stores nothing in the browser. | Nothing to refuse |
How to refuse or remove cookies
Refusing advertising cookies does not remove advertising and does not lock any part of this site. It changes how the ads are chosen. Your options:
- The consent banner. In the EEA, UK, and Switzerland, a banner appears before any advertising cookie is set. Choosing to refuse is honoured, and you can change the answer later from the privacy settings link in the footer.
- Google's own control.Google Ad Settingsturns off ad personalisation across every site Google serves, not just this one.
- Industry opt-outs. Refuse many vendors at once ataboutads.info,optout.networkadvertising.org, oryouronlinechoices.eu.
- Your browser. Chrome, Safari, Firefox, and Edge can all block or delete third-party cookies from their settings, which applies everywhere and does not depend on any site cooperating.
- Global Privacy Control. Browsers and extensions that send theGPCsignal have it treated as an opt-out of targeted advertising.
One caveat worth knowing: opt-out choices are themselves usually stored in a cookie, so clearing all cookies can clear the opt-out along with everything else.
