The companies that we use that generate these cookies have their own, very strict, privacy policies but we don’t have access to these cookies; other than allowing them to be served, we have no role to play in these cookies at all (although we may use statistical information arising from these third party cookies and provided to us by third parties, to improve the targeting of advertisements to users). If you wish to block third party cookies, you can do so in your browser’s security settings – indeed, the majority of browsers will block them by default.
To help you manage your cookies efficiently, all browsers provide you with tools to control your cookies, allowing you to keep them (permanently or for some duration) or delete them entirely.
We recommend the “About cookies” website, published by an independent body, as a good source of information about cookies and how you may best organise yours. In particular, these pages:
Deleting your cookies: https://www.aboutcookies.org/how-to-delete-cookies/
Cookies Law: https://www.aboutcookies.org/cookie-law/
There are, of course, many other websites providing similar information which you may chose to consult as well.
