1Who we are
Quantanite UK Limited is registered under company number 10509140. Our registered office is 45 Albemarle Street, 3rd Floor, London W1S 4JL, United Kingdom. You can contact us about cookies and privacy at [email protected].
2Cookies and similar technologies
Cookies are small text files stored on your device when you use a website. They can help a site operate, remember choices, understand visits or support advertising.
Similar technologies include pixels, tags and browser storage. For example, a pixel or tag can send information about a page view or other event to a provider, while browser storage can retain information on your device. Some technologies transmit or access information without creating a conventional cookie. This policy covers those technologies as well.
First-party cookies are set for the domain of the website you are visiting. Third-party cookies are set for a different domain. A third-party service provider may also use first-party cookies on our website. Session cookies normally last until your browsing session ends. Persistent cookies remain until their expiry date or until they are deleted. Some browser storage remains until it is cleared.
3Why we use these technologies
| Category | Purpose | Your choice |
|---|---|---|
| Strictly necessary | Operating and securing the website, maintaining a requested session or feature, and remembering your cookie choices. A technology belongs here only where its purpose meets the applicable exemption. | These remain active when required and are not controlled by the optional-cookie switches. |
| Optional functionality | Remembering optional preferences or supporting additional features beyond what is necessary for a service you request. | Activated with your consent under our chosen cookie setup. |
| Analytics | Understanding visits and website interactions so that we can assess performance and improve the website. | Activated with your consent under our chosen cookie setup. |
| Advertising | Measuring advertising results and showing relevant advertisements, including to previous website visitors. | Activated with your consent. |
We use a consent-based approach for optional analytics, advertising and functionality. We activate those technologies only after the relevant consent has been given. Simply continuing to browse does not count as consent.
Some technologies become necessary when you actively request a feature, such as submitting an enquiry. Any separate analytics or advertising purpose associated with that feature remains subject to your optional-cookie choices.
4Services used on the website
The technologies used depend on the pages and features you use and the choices you make. The following services support our website and its related functions:
| Service | Role and relevant technologies |
|---|---|
| HubSpot | Enquiry forms, contact management and optional visitor tracking. Technologies used to provide a requested form, preserve a preference or analyse visits can have different purposes and are treated accordingly. |
| Google Analytics | Optional measurement of visits and interactions using online identifiers and event information. |
| Google Tag Manager | Deployment and management of website tags. The tags it loads determine which tracking technologies and data transfers take place. |
| Google Ads | Optional advertising measurement and advertising to relevant audiences, including people who have visited the website. |
| LinkedIn Insight Tag and LinkedIn Ads | Optional campaign measurement, website audience analysis and advertising to relevant audiences, including previous visitors. |
| Cloudflare | Streaming the video on our homepage, and bot protection on services we embed, such as HubSpot forms. Cookies or similar technologies depend on the streaming features enabled. |
| Hotjar | Optional analysis of how visitors use pages, such as heatmaps and visit recordings, to improve the website. |
| Google reCAPTCHA | Protection of the enquiry form against spam and automated abuse. Needed to provide the form you choose to submit. |
Google and LinkedIn advertising technologies can receive online identifiers, device or browser information and information about your website activity. Where relevant, providers may associate that information with other information they hold under their own privacy notices. We do not upload our website enquiry or marketing contact lists to advertising platforms.
Hosting or domain services do not automatically place cookies on visitors' devices. The detailed inventory below identifies the technologies actually deployed, including those used by embedded services.

A provider may use different cookies or durations depending on the configuration of its service. Browser settings can also affect how long a cookie remains on your device. The duration of a cookie is separate from how long personal information collected through it is retained; see our Website Privacy Policy for our retention approach.
6How to make and change your choices
When the cookie controls are first shown, you can choose:
Accept all to allow optional cookies and similar technologies for the purposes displayed.
Reject optional cookies to continue with only technologies needed for the website or a feature you request.
Manage preferences to choose which optional purposes to allow.
You can reopen Cookie settings from the website footer at any time to change your choices or withdraw consent. Refusing or withdrawing consent is as easy as giving it. A change applies to future use of the relevant optional technologies and does not affect the lawfulness of processing carried out before withdrawal.
Withdrawing consent does not necessarily remove information already stored on your device or delete information already held by a provider. You can clear stored cookies and browser data through your browser settings and use the rights described in our Website Privacy Policy for personal information.
You can also block or delete cookies through your browser. Blocking all cookies, including necessary ones, may affect website features. If the enquiry form is unavailable, you can contact us at [email protected].
Choices made on this website apply to this website. If you follow a link to another website, that service provides its own privacy information and controls. Your choices are saved in a cookie on the browser and device you used. We do not keep a central record of them, so you may need to make your choices again on a different browser or device, or after clearing your cookies.

You can find further information about the services we use in the following official notices. These explain the providers' services generally; our cookie declaration and settings describe the configuration used on this website.
8Changes and contact
We may update this policy when the website, its technologies or applicable requirements change. The latest version will be published with an updated date. Where a new optional purpose requires consent, we will ask for that consent before using the technology for that purpose.
