Cookie notice
Last updated: 4 August 2026 · In effect from: 4 August 2026
1. What a cookie is
A cookie is a small text file that a site asks your browser to store, so that something can be remembered between page loads. Similar technologies — local storage, session storage and the storage used by a service worker — do much the same job, and this notice covers them as well.
2. The categories we use
Necessary
These make the site work and cannot be switched off from here. They carry no advertising value: they remember your answer to the cookie banner, keep the interface consistent, and let the browser fetch the files it needs.
Analytics
These count visits and show which entries are read, in aggregate. They are only set once you accept optional cookies.
Advertising
These serve the advertising placements shown on the site: limiting how often the same item appears, and measuring whether a placement was seen. They are only set once you accept optional cookies.
3. What is stored
| Name | Category | Purpose | Lifetime |
|---|---|---|---|
| tp-cookie-choice | Necessary | Stores whether you accepted or declined optional cookies, so the banner is not shown again. | Local storage, until you clear site data |
| OneSignal subscription entries | Necessary for alerts | Set once you allow browser notifications. Hold the push subscription identifier and the state of the permission prompt, so alerts can be delivered and not repeated. | Browser storage, until permission is revoked or site data is cleared |
| Service worker cache | Necessary for alerts | Registers OneSignalSDKWorker.js so a notification can be received while the tab is closed. | Until the worker is unregistered |
| Audience measurement | Analytics | Aggregated counts of page views and entry popularity. | Up to 13 months |
| Placement identifiers | Advertising | Frequency capping and measurement for advertising placements shown on the site. | Up to 13 months |
Exact names in the third-party categories are set by the partner concerned and can change when they update their software. The categories above describe the purpose, which does not change.
4. The consent banner
On a first visit a banner offers Accept and Decline. Your answer is written to local storage under tp-cookie-choice and the banner stays away afterwards. Declining leaves only the necessary entries in place. To be asked again, clear this site's data in your browser and reload the page.
5. Push notifications and OneSignal
Alerts are delivered through OneSignal, which acts as our processor. If you allow notifications, OneSignal stores a subscription identifier in your browser and registers a service worker at /OneSignalSDKWorker.js. That identifier lets us send a message about a new or re-tested entry; it does not tell us who you are. Revoking notification permission in the browser ends the delivery. What we hold and for how long is set out in the privacy notice.
6. Switching cookies off
- In this site: decline optional cookies in the banner, or clear site data and answer again.
- In your browser: every major browser lets you block or delete cookies for a single site or for all sites, usually under Privacy or Site settings. Blocking necessary entries may stop parts of the site from behaving as intended.
- For notifications: open the site settings for this domain in your browser and set notifications back to “Ask” or “Block”.
7. Fonts and other requests
The site loads a web font from a content delivery network. That request is not a cookie, but it does reach a third-party server, which sees the request as part of delivering the file. No advertising identifier is set by that request.
8. Changes
If the set of cookies changes, this page is updated and the date at the top changes with it. Where the change affects optional categories, the banner is shown again so you can answer for the new set.
