Last updated: 24 September 2026. This Cookie Policy should be read together with our Privacy Policy.
1. Information about cookies on our website
1.1. Most websites you visit will use cookies in order to improve your user experience by enabling that website to ‘remember’ you, either for the duration of your visit (using a ‘session cookie’) or for repeat visits (using a ‘persistent cookie’). Cookies do lots of different jobs, like letting you navigate between pages efficiently, storing your preferences, and generally improving your experience of a website. Cookies make the interaction between you and the website faster and easier. If a website doesn’t use cookies, it will think you are a new visitor every time you move to a new page on the site. Some websites will also use cookies to enable them to target their advertising or marketing messages based for example, on your location and/or browsing habits. Cookies may be set by the website you are visiting (‘first party cookies’) or they may be set by other websites who run content on the page you are viewing (‘third party cookies’).
2. What is in a cookie?
2.1 A cookie is a simple text file that is stored on your computer or mobile device by a website’s server and only that server will be able to retrieve or read the contents of that cookie. Each cookie is unique to your web browser. It will contain some anonymous information such as a unique identifier and the site name and some digits and numbers. It allows a website to remember things like your preferences or what’s in your shopping basket.
3. What to do if you don’t want cookies to be set?
3.1 Some people find the idea of a website storing information on their computer or mobile device a bit intrusive, particularly when this information is stored and used by a third party without them knowing. Although this is generally quite harmless you may not, for example, want to see advertising that has been targeted to your interests. If you prefer, it is possible to block some or all cookies, or even to delete cookies that have already been set, but you need to be aware that you might lose some functions of that website.
4. How we use cookies and similar technologies
4.1 We use analytics cookies from Google Analytics only if you accept them in our cookie banner. If you reject them, or have not made a choice, no analytics cookies are set and Google Analytics is not loaded. We do not use advertising cookies.
4.2 Google Analytics helps us understand how visitors use our website - for example, which pages are visited and for how long - so we can improve it. The information is aggregated and we do not use it to identify you. Google processes this information on our behalf; see how Google uses information from sites that use its services. If you accept, Google Analytics sets the following cookies:
- _ga - used to distinguish unique visitors. Expires after 2 years.
- _ga_7VZXECLV4H - used to maintain the state of your visit. Expires after 2 years.
4.3 We save your cookie choice in your browser’s local storage (under the name ‘ph_cookie_consent’) so we do not ask you again on every page. This is strictly necessary to respect your choice.
4.4 If you choose a colour theme (light or dark) using the control in the website header, your choice is saved in your browser’s local storage (under the name ‘ph_theme’) so the website remembers it on your next visit. This is only stored because you asked for the preference to be remembered. It never leaves your device and is not used to identify or track you. You can clear it at any time through your browser settings.
5. Third-party services
5.1 Our website uses fonts provided by Google Fonts. To display them, your browser connects to Google’s servers, which receive your IP address. Google Fonts does not set cookies. For more information, see Google’s privacy policy.
6. Changing your choice
6.1 You can change or withdraw your consent at any time using the Cookie settings link at the bottom of every page. If you withdraw your consent, we delete the Google Analytics cookies set on our website.
6.2 If we introduce any other non-essential cookies in the future, we will update this policy and ask for your consent before setting them, as required by the Privacy and Electronic Communications Regulations 2003 (PECR).
