CPMS Cookie Policy

Content last updated:  28 July 2025. 

What is a cookie?

A cookie is a small text file that is downloaded onto your device (computer, tablet, or smartphone) when you visit our website. It allows us to recognise your device and store some information about your visit or past actions.

Why do we ask to put cookies on your device?

By aggregating data from all our website visitors, we can better understand what content our visitors find useful and what content needs to be improved. By allowing cookies onto your device you are helping us continually improve the Central Portfolio Management System (CPMS) for everyone.

What types of cookies do we use?

• Strictly Necessary (Functional) cookies - these are needed to make the website work.

• Additional (optional) cookies, including performance cookies, to give us insight into how people use our content and help us improve it.

Can I decide to reject cookies?

Not at the moment.  RDNCC is working on implementing this functionality in CPMS.

To opt out of being tracked by Google Analytics across all websites, visit the Google Analytics Opt-out Browser Add-on. 

Do you collect and can you see my personal data?

No. We don’t collect, store, or process any personally identifiable information such as your name or address, so this information cannot be used to identify who you are. We only see anonymised, aggregated data. But they will use your computer's IP address to determine your approximate geographical location (so we can understand where in the world users are located).

The data stored in Google Analytics is anonymous and we do not allow Google Analytics to share the data about how you use the Central Portfolio Management System (CPMS).
