A cookie is a small text file that a website stores on your computer or mobile device when you visit a website. This allows the website to remember your actions and choices (sign-up, language, font size and other display choices) over time, so you don't have to re-enter them each time you return to the site or navigate from one page to another.
Other cookies allow you to track website traffic and user interactions with the website - we use this data to analyze visitor behavior and improve the visitor experience. These cookies are stored and used by the Google Analytics tool. Here you can learn more about how Google Analytics works and what information it collects and analyzes - https://support.google.com/analytics/answer/1012034?hl=en&ref_topic=6157800.
You can control and / or delete cookies of your choice - see www.youronlinechoices.com for more information. You can delete all cookies already stored on your computer, and you can set your browser to prevent them from being stored. But in that case, you have to manually specify a choice each time you visit the site, and some services and features may not work.
You can stop collecting your data in Google Analytics at any time, as described here: https://tools.google.com/dlpage/gaoptout/.
