How we use cookies

Last updated 16 August 2026. This notice covers cellandgene.live, operated by Onyx Newsroom Ltd.

This site is close to cookie-free by design. We run no advertising cookies, no social media pixels, and no cross-site tracking of any kind. There is exactly one thing on this site that needs your permission, and you can turn it off again at any time.

What you have a choice about

Intercom (live chat). If you accept, we load Intercom's messenger so you can ask us questions about the summit and pick the conversation back up later. It sets several cookies named intercom-id-, intercom-session- and intercom-device-id-, and stores your conversation state in your browser's local storage (under intercom. and ably-, the latter belonging to the service that keeps the chat live), so it can recognise your conversation when you come back. The cookies typically last up to nine months. Intercom Inc. acts as our processor and its servers may be outside the UK; where that happens we rely on UK adequacy regulations or the UK International Data Transfer Addendum.

If you decline, the Intercom script is never loaded at all — it is blocked before it runs, not merely hidden. You can still reach us by email and the rest of the site works exactly as it does with chat enabled.

Cookie settings — change your answer at any time. Turning chat off ends the conversation and deletes both the cookies and the local storage entries listed above, in every tab you have open.

What we set without asking

A small number of cookies are strictly necessary — they are what makes the site function when you ask it to do something, and UK law does not require consent for them. We use them for nothing else:

• Your cookie choice itself.Stored in your browser's local storage as onyx_consent_v1. Without it we would have to ask you on every single page.
• Your currency preference (onyx_currency), if you switch currency on the ticket pages. Lasts a year.
• Sign-in session cookies, if you create an account to buy a ticket. Set by Supabase, our authentication provider, and cleared when you sign out.

Payments are handled on Stripe's own checkout pages. We never see your card details, and Stripe's cookies are set on Stripe's domain under its own privacy policy.

Our analytics do not use cookies

We measure how many people visit which pages using Umami, which we host ourselves. It sets no cookies, stores no identifiers on your device, and cannot follow you to another website. That is deliberate — it is why this site had no cookie banner at all until we added live chat.

Controlling cookies in your browser

Every major browser lets you block or delete cookies from its settings, and that applies to this site as much as any other. Note that blocking the strictly necessary cookies above will stop parts of the site working — you would not be able to stay signed in, for example.
