What a cookie is
A cookie is a small file a website stores on your device so it can remember something about your visit. Some are needed for the site to work. Others help us understand how the site is used. Similar technologies — pixels, tags and browser storage — are covered by this policy too.
Your choice
When you first visit we ask which cookies you are happy for us to use. Only the strictly necessary cookies below are set before you choose — nothing in the analytics or advertising sections is set until you agree to it.
You can change your mind at any time: change your cookie settings, or clear this site’s data in your browser and we will ask again. Each section below also lists the provider’s own opt-out where one exists.
Strictly necessary — always on
These are needed for the site to function and do not track you across other websites.
| Cookie | What it does | How long it lasts |
|---|---|---|
PHPSESSID |
Identifies your browsing session so pages behave consistently as you move around the site. | Until you close your browser. |
wordpress_logged_in_*, wp-settings-* |
If you have a subscriber account: keeps you signed in and remembers your display preferences. | Session to 1 year. |
Analytics
These tell us which research and pages are of interest, so we can improve what we publish. We use the results in aggregate and do not use them to identify you.
| Cookie | Set by | What it does | How long it lasts |
|---|---|---|---|
_ga, _ga_* |

You can opt out of Google Analytics on every website using the Google Analytics opt-out browser add-on.
Advertising measurement
Pages on this site contact Google’s advertising measurement service (doubleclick.net), which lets us understand which of our advertising brings people to our research. Google may set cookies on its own domains when this happens. You can review and switch these off in your Google Ad Centre.
Content from other companies
Some pages embed a Vimeo video. Vimeo may set its own cookies when you play it, under Vimeo’s own policy.
Our other websites
Our event and publication sites — including cxsymposium.com and our journal titles — use additional cookies, including advertising cookies. Each has its own cookie policy.
Controlling cookies in your browser
Every major browser lets you block or delete cookies, and blocking third-party cookies will stop most of the analytics and advertising cookies described above. The relevant instructions are here: Chrome, Firefox, Safari and Edge.
Blocking strictly necessary cookies will stop parts of the site working.
