What cookies do we use

Necessary & Functionality Cookies

These cookies are necessary for the website to function. They are usually only set in response to actions made by you which amount to a request for services, such as setting your privacy preferences, logging in or filling in forms.

cookie-agreed Informs you about our cookie use and lets us know whether you've agreed to our use of cookies.
Drupal.toolbar.collapsed Our website content management system stores these to store user interface preferences.
cfduid This cookie is used to identify individual clients behind a shared IP address and apply security settings on a per-client basis. For example, if the visitor is in a coffee shop where there are a bunch of infected machines, but the specific visitor's machine is trusted (e.g. because they've completed a challenge within your Challenge Passage period), the cookie allows us to identify that client and not challenge them again. It does not correspond to any user ID, and does not store any personally identifiable information.
_vwo_uuid This cookie generates a unique ID for every visitor and is used for the report segmentation feature in VWO. It allows us to view data in a more refined manner.
_vwo_uuid_v2 This cookie generates a unique ID for every visitor and is used for the report segmentation feature in VWO. It allows us to view data in a more refined manner.

They can enable certain site functionality and are also used by the server to store/remember information about user web page activities so user information can be stored throughout an online web process e.g. to allow information to be carried across pages of a website to avoid having to re-enter information.

Performance Cookies

These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. They help us to know which pages are the most and least popular and see how visitors move around the site.

All information these cookies collect is aggregated and therefore anonymous. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance.

Cookies used:

Cookie Name Purpose
_ga This cookie is used to distinguishes unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports.
_gid This cookie is used to distinguishes unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports.
_eventqueue This cookie stores an array of mouse events that can't be guaranteed to be logged to our servers before the current page is unloaded. The purpose is to store these events in a queue so on the subsequent page view, these events can be processed and logged. This is a session cookie so it will expire when the visitor leaves our web site.
_first_pageview This cookie is set on the first page view of a session. It is used to make our tracking code more efficient, so certain processes are only run on a visitor's initial page view. It expires after 10 minutes.
_jsuid This is a random number that is generated by the Code the first time someone visits a web site with the Code installed. Its sole purpose is to better identify new and unique visitors to a web site. This cookie is sent to the Service for every event logged. The value of this cookie will also be set as a third party cookie with the name of "cluid", if such a cookie does not exist. The purpose of the third party cookie is for web sites with multiple domains and who want to track visitor sessions across multiple domains, which is not possible with first party cookies. These "uid" cookies are set to more or less never expire.
no_trackyy_100901914 This cookie is set whenever data is sent in for a site that is disabled. It tells our tracking code to stop sending data to us. This cookie expires after 1 hour but will be set again upon future visits by the same visitor, until the Code is removed.
