Use of cookies on OPC website

Cookies are small text files that are placed in your browser by the websites you visit. They are widely used to help users navigate websites efficiently, to perform certain functions on the sites, and/or to provide site owners with information about how their sites are used.

We use cookies on our site where they are required for particular features to work – for example, if you are a logged in user, to allow you to remain logged in whilst you complete certain tasks.

Web analytics cookies:

We also use tracking cookies with the Matomo web analytics tool (see our use of website analytics) to analyse non-identifiable web traffic data to improve our services.  This data is aggregated and cannot personally identify you. If you prefer, you can opt out of the Matomo tracking cookies we use without affecting your ability to use our site. Our web analytics will also respect any “do not track” setting that you might have set on your browser.

You can change your Matomo opt out or opt in setting here. 

Social media cookies

We use social media on some sections of our website to help communicate our messages and give you the best experience – e.g. the Twitter feed on our home page, the Twitter and Facebook plugins on our blog pages, and the YouTube videos we embed.

These social media services have their own privacy policies and may track your use of our website on those pages where their links are displayed. They do this by the use, for example, of persistent session cookies and their tracking may be associated with your profile with them.

Most web browsers will allow you to set some control over cookies in your browser settings. This includes deleting them from your browser or disabling them altogether.

If you do choose to set your browser to disable all cookies, this may affect your ability to use some of the features on our site.
