What this site stores in your browser
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
ld_case_access | Cookie, strictly necessary | Keeps you signed in to the confidential case studies after you enter your one-time code. Set only after you verify an approved access link. HttpOnly, same-site. | Until your access link expires, at most 3 business days |
has-loaded-initial | Session storage, functional | Remembers that the page intro has played once, so it does not replay on every page. Cleared when you close the tab. | Current browser tab |
That is all. There are no analytics, advertising, social media or third-party cookies on this site.
Why there is no cookie banner
Strictly necessary and functional storage does not require consent under the ePrivacy rules, the GDPR or the UK PECR. A banner would ask you to consent to nothing. We have decided not to add analytics. If we ever add a cookie that is not strictly necessary, we will add a consent choice before it loads and update this page.
How to control cookies
You can delete or block cookies in your browser settings. If you block ld_case_access you will need to open your access link and enter a new one-time code each time you open a confidential case study.
