1. What Are Cookies
Cookies are small text files placed on your device (computer, tablet, or mobile) when you visit a website. They are widely used to make websites work, remember your preferences, and provide website owners with information about how their site is used.
Cookies are set either by the website you are visiting (first-party cookies) or by third-party services embedded in the page (third-party cookies). They vary in duration:
- Session cookies — deleted automatically when you close your browser
- Persistent cookies — remain on your device for a set period or until you delete them
2. How We Use Cookies
We use cookies for one purpose only: analytics. Specifically, to understand how visitors navigate our website so we can improve our content and user experience.
Under EU law (the ePrivacy Directive and GDPR), analytics cookies require your prior consent. We implement this through a cookie consent banner that appears on your first visit. If you decline, no analytics cookies are set and no data is sent to Google — we use Google Consent Mode v2 to enforce this technically.
3. Cookies We Set
3.1 Strictly Necessary
These cookies are essential for the website to function correctly. They cannot be switched off. Our website does not currently set any strictly necessary cookies. Standard browser behaviour (such as temporary session storage for form interactions) is handled entirely in your browser without server-side cookies.
3.2 Analytics Cookies (consent required)
These cookies help us understand how visitors interact with our website. They collect information in aggregate and do not identify you personally. We only set these if you have explicitly accepted analytics cookies.
| Cookie | Provider | Purpose | Duration |
|---|
| _ga | Google Analytics | Distinguishes unique users by assigning a randomly generated client identifier. Used to calculate visitor, session, and campaign data. | 2 years |
| _ga_WGDVHMPDHT | Google Analytics | Used to persist session state and track page view sequences for this specific GA4 property. | 2 years |
| _gid | Google Analytics | Distinguishes users. Stores and updates a unique value for each page visited. | 24 hours |
| _gat | Google Analytics | Used to throttle the rate of requests to Google's servers (rate limiting). | 1 minute |
3.3 Local Storage (non-cookie)
We store your cookie consent preference in your browser's localStorage under the key dd_cookie_consent. This stores either granted or declined. Local storage is not a cookie and is not transmitted to our servers — it exists solely in your browser to remember your preference so we don't ask again on every visit.
4. Third-Party Cookies
Google Analytics sets and reads cookies on behalf of Data Dynamics. When analytics cookies are accepted, Google Analytics scripts load from googletagmanager.com and google-analytics.com. Google may also set additional cookies on Google domains for measurement purposes.

- ✓We do not use Facebook Pixel, TikTok Pixel, or any other advertising or remarketing pixel on this website.
- ✓We do not use cookies to build advertising profiles or to serve targeted ads based on your behaviour on our site.
- ✓We do not sell or share cookie data with advertisers.
- ✓We do not use cross-site tracking technologies.

6. Managing Your Cookie Preferences

7. Changes to This Policy
