Cookies and storage
Professional clinical website · study closed · reviewed: 15 September 2026
Scope reviewed for publication. This notice describes current decisions and limitations; it is not legal advice, regulatory authorisation or clinical certification.
Visual preference
The application uses localStorage with the key theme to remember your selected light or dark theme. It remains until you clear it or the browser removes it. Without a saved choice, the device visual preference is used.
Clinical notice during the session
Accepting the clinical notice stores ibd_disclaimer_accepted in sessionStorage for the tab session. It contains no calculator measurements. The component also attempts to remove the old persistent acknowledgement from localStorage; this does not clear other browser data or cookies.
Internal QA
Internal quality assurance requires authorised access. If used, it may store reviewer information and answers locally until cleared in that browser. It is separate from the public calculator; do not enter patient data.
Study closed
The study remains closed in this release: the application does not create new study sessions or cookies and does not accept new study participation or submissions. This does not delete data or cookies that may remain from earlier versions; they require separate management.
Advertising and hosting
The reviewed code and public page do not load advertising cookies, Vercel Web Analytics, Speed Insights or third-party analytics. Vercel still generates technical data needed to deliver and protect the service; see the privacy policy.
Managing storage
You can clear site data in your browser settings. This removes your theme choice. Local data or cookies from earlier versions may remain; this release does not automatically delete them. Clearing browser data does not delete emails already sent or data that may exist on servers.
