What are cookies?
A cookie is a small file containing a string of characters that is sent to your computer when you visit a website. Each time you return to the same website, your browser retrieves and sends the relevant cookie(s) to the website’s server.
First party cookies are cookies set by the website you’re visiting. Only that website can read them. In addition, a website might potentially use external services, which also set their own cookies, known as third-party cookies.
Persistent cookies are cookies saved on your computer and that are not deleted automatically when you quit your browser, unlike a session cookie, which is deleted when you quit your browser.
Cookies help us to improve our website and to deliver a better and more personalized service, for instance by storing information about your preferences and allowing us to recognize you when you return to our website.

Google Analytics is a simple, easy-to-use tool that helps website owners measure how users interact with website content. As a user navigates between web pages, Google Analytics provides website owners JavaScript tags (libraries) to record information about the page a user has seen, for example the URL of the page.
The Google Analytics JavaScript libraries use HTTP cookies to "remember" what a user has done on previous pages / interactions with the website.
