Cookie and Privacy Policy

This page describes our policy for handling the personal information (also known as personal data) collected when you visit this website ( The policy is limited to the information collected and used by the MRC CBU from visitors to this website. Other policies will apply to other types of personal data, for example data collected from participants in scientific studies, or from job applicants. For details of our policy regarding data collected from participants in scientific studies, please see this page

What data does this site collect?

In common with most web sites, this site automatically logs certain information about every request made of it. Further details of the information that is logged are included below. This information is used for system administration, for bug tracking, and for producing usage statistics. The logged information is currently retained for no longer than 1 year.

We may use and disclose logged information as necessary in the event of a security concern or incident, or to ensure the proper operation of the site. For example:

  • Subsets of the data may be passed to third parties as part of investigations of computer misuse involving this site or of other equipment belonging to the MRC CBU or its parent organisation.
  • Data may be passed to the administrators of other computer systems to enable investigation of problems affecting this site.
  • Data may also be included in information passed to contractors and computer maintenance organisations working for the MRC CBU or its parent organisation, in which case it will be covered by appropriate non-disclosure agreements.

We also use a third party service, Google Analytics, to collect information and details of visitor behaviour patterns. We do this to monitor the way the site is used, for example to track the number of visitors to particular parts of the site or to track the geographic location of visitors to the site. Google Analytics have their own policies describing how they will use the information that is sent to them. Further details are available here and here. This site has requested that Google Analytics anonymise the information we send to them about visitors’ IP addresses. This means that it will be impossible to identify the records associated with individual visitors to this site from the data held by Google.

Otherwise the logged information will not be passed to any third party except as required by law. Summary statistics are extracted from this data and some of these may be made publicly available, but these will not include information which would allow individual visitors to the site to be identified.

The use of your personal information in the above ways is necessary for the legitimate interests of the MRC CBU in operating and improving its websites, analysing their use, and ensuring their security. Our websites collect very little personal information and we use it in ways that are compatible with your individual rights and freedoms. Where you enter your personal information into an online form on any of our websites for any specified purpose, you will be told how we will use that information (e.g. to send you newsletters or to enable your attendance at an event).

Logged data

The following data is automatically logged for each request:

  • The name or network address of the computer making the request. Note that under some (but not all) circumstances it may be possible to infer from this the identity of the person making the request. Note also that the data recorded may be that of a web proxy rather than that of the originating client
  • The username, when known during authenticated (logged in) access to the site
  • The date and time of connection
  • The HTTP request, which contains the identification of the document requested
  • The status code of the request (success or failure etc.)
  • The number of data bytes sent in response
  • The contents of the HTTP Referrer header supplied by the browser
  • The content of the HTTP User-Agent header supplied by the browser

Logging of additional data may be enabled temporarily from time to time for specific purposes. In addition, the computers on which the web site is hosted keep records of attempts (authorised and unauthorised) to use them for purposes other than access to the web server. This data typically includes the date and time of the attempt, the service to which access was attempted, and the name or network address of the computer making the connection.
