Cookie policy
Last updated: 12 October 2026.
Necessary cookies
wcm_csrf protects forms from cross-site requests and lasts up to 24 hours. wcm_session supports private staff sign-in, with an eight-hour staff session. These cookies are Secure on HTTPS, HttpOnly and SameSite=Lax. Signing out invalidates the staff session. Public search and reporting do not require an account.
Reading preferences
wcm_theme stores a chosen light or dark appearance. wcm_reading stores the chosen font and text size. Both use local storage on your device and remain until changed or cleared through your browser. They do not track you across websites.
Form security
Public forms use Cloudflare Turnstile to assess automated traffic. See Cloudflare’s Turnstile privacy information for its processing. The application verifies the response on the server before accepting a submission.
Advertising choices
Advertising is disabled until the publisher and certified consent platform are configured. Where enabled, Cookiebot presents the choices and the application waits for the required Google vendor and advertising-purpose consent before requesting an ad. No advertising request is made when the required consent is absent. Details of the configured vendors and storage are available through that consent interface.
Change or clear your choices
Select Cookie settings in the footer to reopen the active consent platform. If no advertising platform is configured, the control explains necessary storage. Withdrawal blocks future loading and reloads pages that have already loaded advertising. Clearing site data in your browser removes reading preferences and signs staff out. Read our privacy policy for other processing.
Mobile app storage
The iPhone and Android apps use app preferences for recent searches and hidden-report choices, and Google’s consent and advertising SDKs can use device storage. This is separate from browser cookies. Use More → Advertising privacy choices where available for app advertising choices, Clear recent searches for local history and Restore hidden reports for local hiding choices. Website pages opened from an app use the website controls described above. See the mobile-app section of our privacy policy for purposes, data types and deletion options.
