Cookies

Last updated: 9 September 2026. Porthole only uses cookies that are needed to run the service.

Essential cookies

• porthole_session — keeps you signed in. HttpOnly; set when you sign in and cleared when you sign out.
• porthole_profile_incomplete — soft gate after invite accept / first sign-in until phone, date of birth, and next of kin are saved. Cleared when the profile is complete or you sign out.
• nci-display — remembers large print, contrast, and theme choices between visits.

Local storage

Your theme preference may also be stored in the browser via localStorage (key theme). Cookie consent itself is stored as porthole_cookie_consent so we do not keep asking on every visit.
