Cookies on our website

To help improve this site we may place small data files, known as cookies, onto your computer, smartphone or other internet device. Cookies are used by most websites to help personalise your web experience.

We use two different types of cookie.

  • 'necessary' cookies which remember that you've logged in and what your cookie preferences are
  • analytics cookies which measure how you use the website, without identifying you personally, so we can make sure it meets your needs. These are optional.

We also use Facebook's Conversion Tracking Pixel - see below for more information.

Necessary cookies

Our member login system sets a temporary 'session cookie' to allow it to run smoothly. This is classed as strictly necessary to the operation of our site, so you can't opt out of it. You can disable it by changing your browser settings to not accept it, but this means that some parts of the site won't work. We also use a cookie which records that you've accepted cookies. These are the necessary cookies:

Name Expiry Application Description
prs End of session Website Session cookie to maintain your browsing session
TabViewSelectedTab  1 year  Website Records which tab you last viewed for tabbed content
analytics 90 days Website Records whether you have opted to allow analytics cookies to be set

Optional cookies

We use analytics to collect anonymous information about how people use our site. An analytics cookie records which pages you visit, how long you are on the site, how you got here and what you click on. It also records your general geographical vicinity, and information about your browser and operating system. It does not collect or store any personal information about you (eg your name or address) so it doesn't identify who you are.

Facebook conversion tracking pixel

With your permission, our website uses Facebook's Conversion Tracking Pixel. This enables us to find out how many people have visited our website after clicking on an advert they've seen on Facebook.  We use this for statistical and marketing purposes, to help us assess the effectiveness of our Facebook ads. The collected data we receive is anonymous – Prospect cannot see the personal data of any individual user. However, Facebook also saves and processes the collected data. It can connect this with your Facebook account and use it for its own advertising purposes, in accordance with its own Data Use Policy. Facebook Conversion Tracking also allows Facebook and its partners to show you advertisements on and outside Facebook. A cookie will also be saved onto your computer for these purposes. 

You can revoke your permission for Facebook to use its Conversion Tracking Pixel at

Only users over 13 years of age can give their permission for the Facebook Conversion Tracking Pixel. If you are younger than 13, please consult your legal guardians.
