Some people find the notion of information being stored on their computer or mobile device a little intrusive, in particular when that information is stored and used by a third party without their knowledge. If you prefer, it is possible to block some or all cookies, or even delete cookies which have already been set, but you should be aware that you might lose some functions. To do this, you need to alter your browser privacy settings.
Some third-party operators have developed tools for disabling data collection and use via their modules.
