Cookies and Browser Storage

This site uses a small number of cookies and similar browser storage items to make the service work.

We do not use them for advertising, and we do not use them to track you across other websites.

Cookies

timezone

Stores your browser's timezone so dates and times can be shown in your local time. This is a session cookie.

KSESSIONID

Keeps you signed in during your current session. Expires after 30 minutes.

KREMEMBERME

Keeps you signed in between visits if you choose to stay signed in. It is set for 90 days at a time and is renewed when it is used to sign you in again.

KDEVICEID

Stores a device identifier to support remember-me functionality. It is stored indefinitely, which in practice is around 20 years in the current implementation.

KID

Stores your user ID to support remember-me functionality by linking the browser to the signed-in account. It is stored indefinitely, which in practice is around 20 years in the current implementation.

KVIEWINGMODE

Stores stores your viewing mode preferences locally, because these may differ on each computer you use.

Browser storage

The following are stored in session storage.

KINSTANCEID

Stores an identifier for the current browser tab, so separate tabs can behave independently. It lasts until the browser tab or session ends.

KCSRFTOKEN

Stores a token used to prevent cross-site request forgery attacks on the site.

The following is stored in local storage.

KCLIENTBUNDLEVERSION

Stores the version of the client script last loaded by this browser, so the site can tell you when a newly deployed version has just loaded.

Why we use these

These items are used for signing you in, keeping you signed in if you ask us to, associating your browser with your account securely, maintaining security whilst using the application, showing dates and times in your local timezone, and letting you know when a newly deployed version of the site has loaded.
