What cookies do
Cookies are small pieces of information stored by your browser. Similar technologies, such as session storage, can also remember information while you use a website.
We use necessary storage to support website functions and remember your privacy choices. We may use optional Google Analytics cookies to understand website activity, but only if you allow analytics and the service is enabled.
Your choice comes first
You can accept or reject optional analytics in the cookie notice, or choose your preference in Cookie settings. Optional analytics is off until you allow it. Rejecting it does not stop you browsing the site or sending an enquiry.
We remember your choice for up to 180 days. We may ask again when it expires, if you clear browser storage or if the purposes change materially. Closing the preferences window without saving leaves your existing choice unchanged.
You can change or withdraw your choice at any time using in the footer. Withdrawal stops this website’s analytics and removes its accessible analytics cookies from your browser. It does not delete information already collected; contact us if you want to discuss your data rights.
Cookies and browser storage
| Name | Purpose | Duration |
|---|---|---|
hann_cookie_consent_v1Necessary | Remembers whether you allowed optional analytics. Contains your choice and timestamps, not your enquiry details. | Up to 180 days |
wpEmojiSettingsSupportsFunctional session storage | Remembers whether your browser supports the site’s emoji display features. It is not used to track visits. | Browser session |
| WordPress sign-in cookies Authorised users only | Support secure administrator sign-in and account preferences. These are not required for ordinary visitors to browse the public site. | Session or the selected sign-in / preference period |
hann_ga and hann_ga_*Optional Google Analytics | When Analytics is enabled and allowed, distinguish visits and maintain session information to help measure website use. These are this site’s prefixed versions of Google’s _ga cookies. | Up to 180 days in this website’s setup |
Analytics cookies are not set simply because they are described here. They require both an enabled Analytics service and your permission.
Google Analytics and Search Console
Google Analytics 4: if enabled, this optional service helps us understand visits, popular pages, device types and referral sources. The Google tag is held back until analytics is allowed. This website’s setup disables advertising personalisation and Google Signals.
Google Search Console: we may use this to review search visibility and indexing. Verification through a DNS record or HTML verification tag does not set visitor-tracking cookies on this website and does not require an analytics opt-in. Using Search Console does not override your Google Analytics preference.
For further details, see how Google uses cookies and Google’s Privacy Policy.
Browser controls
You can also delete or block cookies through your browser settings. Clearing the consent cookie means we will ask for your choice again. Blocking necessary storage may prevent your choice being remembered or affect sign-in features.
Your preferences apply to the browser and device you are using. If your browser prevents us from saving the preference, your choice applies to the current page and you may see the notice again.
