Information collection

When you visit websites hosted at CERN, including reading or downloading material, CERN’s servers automatically record information (“log data”) which may include resource usage, IP addresses, information about what type of browser and operating system you are using and digital access information.

On certain websites, including registration pages, recruitment pages and questionnaires, you may be asked to provide additional information, such as email addresses.

Log data is collected through various technologies, including “cookies” and session data, whereby the following information is associated with the cookie: IP address, unique identifiers and status information. This data is also used to track your usage of CERN websites.

Use of collected information

CERN uses log data to operate, customize and improve its websites; measure user activity as well as for security monitoring purposes. Log data may be preserved indefinitely.

Access to personal data, right to correction and deletion

If you have provided personal data to CERN via its websites you may request at any time access to such data, subject to you also providing CERN with proof of your identity.

You may further request at any time that, with reasonable efforts, CERN corrects your personal data in case of proven factual error, or that CERN deletes such data.
