This Cookie Policy explains how OneCarbon (a trading name of Healthspan Biotics Limited) uses cookies and similar technologies when you visit onecarbon.com. It should be read alongside our Privacy Policy.
By continuing to use our website you agree to our use of cookies as described in this policy. You can withdraw or change your preferences at any time — see Managing your cookies below.
Cookies are small text files that a website stores on your device (computer, tablet, or mobile) when you visit. They allow the website to remember information about your visit — such as items in your cart or your preferred language — and can make your next visit easier and the site more useful to you.
Similar technologies include web beacons, pixel tags, and local storage. For simplicity we refer to all of these collectively as "cookies" in this policy.
Cookies are set either by us (first-party cookies) or by third parties whose services we use on our pages (third-party cookies).
We use cookies to:
Strictly necessary cookies do not require your consent under PECR and UK GDPR because they are essential for the website to function. All other cookie categories require your consent before we set them.
These cookies are required for the website to operate and cannot be switched off. They are set in response to actions you take, such as saving your cookie preference. They do not store any personally identifiable information.
| Cookie name | Provider | Purpose | Expiry |
|---|---|---|---|
| cookie_consent | onecarbon.com | Stores your cookie preference so you are not asked again | 6 months |
These cookies enable enhanced functionality. They are set by third-party services embedded on our pages. If you disable these cookies, some features may not work as intended.
| Cookie name | Provider | Purpose | Expiry |
|---|---|---|---|
| YSC | YouTube (Google) | Registers a unique ID to track statistics of videos watched on our Research page | Session |
| VISITOR_INFO1_LIVE | YouTube (Google) | Estimates user bandwidth on pages with embedded YouTube video | 6 months |
| GPS | YouTube (Google) | Registers a unique ID on mobile devices to enable tracking based on geographical GPS location | 30 minutes |
These cookies are set automatically when the YouTube video on our Research page loads. See Google's Privacy Policy for details.
We use Google Analytics 4 to understand how visitors find and use this website — which pages are read, how people arrive, and where they leave. This helps us improve the site.
These cookies are only set if you accept them. No analytics cookies are placed on your device unless you choose "Accept analytics" on the banner shown on your first visit. If you reject, or simply ignore the banner, Google Analytics is never loaded at all — we do not merely place it in a restricted mode.
Google Analytics 4 does not store full IP addresses. We do not use it for advertising, and we do not share this data with third parties for marketing purposes.
| Cookie name | Provider | Purpose | Expiry |
|---|---|---|---|
| _ga | Google Analytics | Distinguishes one visitor from another | 2 years |
| _ga_<container-id> | Google Analytics | Maintains the state of your visit (session) | 2 years |
You can change your mind at any time — see Managing your cookies below. Withdrawing consent removes the analytics cookies already set.
When you arrive from a link we have tagged for a campaign (for example from a newsletter or a social post), we record which campaign it was, so that if you later submit one of our forms we can tell which campaign led you to us. This is stored in your browser's session storage, not in a cookie: it is limited to that browser tab, is cleared when you close it, is never sent to any other website, and does not identify you. It is not used to track you across sites or to build a profile.
We use the Meta (Facebook) Pixel to measure the performance of our advertising and understand which ads lead people to this site.
These cookies are only set if you accept them. No marketing cookies are placed on your device unless you choose "Accept analytics" on the banner shown on your first visit. If you reject, or simply ignore the banner, the Meta Pixel is never loaded at all.
| Cookie name | Provider | Purpose | Expiry |
|---|---|---|---|
| _fbp | Meta Pixel | Identifies browsers for ad delivery and measurement | 3 months |
| _fbc | Meta Pixel | Records the Facebook ad click that led to this visit, if any | 3 months |
You can opt out of Meta's use of cookies for ad personalisation by visiting Meta's ad settings. See Meta's Privacy Policy for details.
Some pages on our website use services provided by third parties that may set their own cookies. We do not control these cookies and they are governed by the respective third party's privacy and cookie policies.
Our "Buy now" buttons link to buy.stripe.com, which is hosted by Stripe Payments Europe Limited. Stripe may set cookies on their own domain when you complete a purchase. These cookies are set by Stripe, not by us, and are governed by Stripe's Privacy Policy. No Stripe cookies are set on onecarbon.com.
Our contact, PROFILE sign-up, mailing list and waiting list forms submit via Formspree, a third-party form delivery service. Formspree may set short-lived cookies on their own domain to handle spam protection (including reCAPTCHA) and submission validation. No persistent cookies from this service are set on onecarbon.com.
We load fonts from Google Fonts to render text on our website. Google may receive your IP address and browser information when your device downloads the fonts, but does not typically set persistent cookies in this context. See Google's Privacy Policy for details.
We use Font Awesome (via Cloudflare CDN) for icons on this website. No cookies are set by Font Awesome in this usage.
