Your Consent
When you first visit, a banner asks whether you accept optional cookies. We do not load any analytics or marketing technologies until you click Accept. If you click Decline — or simply ignore the banner — no analytics or marketing cookies are set, and the site continues to work normally using only the strictly necessary items.
Strictly Necessary Cookies
These are required for the site to function — to remember your consent choice, keep your cart, and support the age-verification gate. They do not track you across other sites and cannot be switched off, as the site would not work correctly without them.
| Name / Provider | Purpose | Type & Duration |

| bhl_age_verifiedBioHack London | Records that you have confirmed you are 18 or over on the age-verification gate, so it is not shown again during the same browsing session. | First-party session storage · cleared when you close the browser tab/window |
| biohack_cartBioHack London | Stores the contents of your shopping cart so your items are retained as you browse and return to checkout. | First-party local storage · persists until you clear it or empty your cart |

Managing Your Consent
You are always in control of the optional cookies described above:
- Change or withdraw consent: click “Cookie Settings” in the footer of any page to reopen the banner. Withdrawing is as easy as giving consent — declining blocks all non-essential (analytics and marketing) cookies.
- Browser controls: most browsers let you block or delete cookies and clear site storage. Doing so may reset your preferences (including your consent choice) and can affect how parts of the site work.
- Advertising opt-outs: you can also manage ad personalisation directly with the providers — for example through your Google and Meta account settings.
