A cookie is a piece of information in the form of a very small text file that is placed on an internet user's device storage. It is generated by a web page server, which is basically the computer that operates a web site. The information the cookie contains is set by the server and it can be used by that server whenever the user visits the site. A cookie can be thought of as an internet user's identification card, which tell a web site when the user has returned.
Session Cookies are stored in the device memory only during a user's browsing session and are automatically deleted from the user's device when the browser is closed. These cookies usually store a session ID that is not personally identifiable to users, allowing the user to move from page to page without having to log-in repeatedly.
Session Cookies are never written on the device hard drive and they do not collect any information from the user's device. Session cookies expire at the end of the user's browser session and can also become no longer accessible after the session has been inactive for a specified length of time, usually 20 minutes.
Stored Cookies are stored on the user's device and are not deleted when the browser is closed. Permanent cookies can retain user preferences for a particular web site, allowing those preferences to be used in future browsing sessions.
Permanent cookies can be used to identify individual users, so they may be used by web sites to analyse users' surfing behaviour within the web site. These cookies can also be used to provide information about numbers of visitors, the average time spent on a particular page and generally the performance of the web site.
Third Party Cookies are not set directly by Chris Watterston, but by third-party providers. Third Party Cookies may be set by providers whose services or functionality is embedded in the Chris Watterston websites.

Analytics: We use Google Analytics, which creates a number of first-party cookies, all prefixed __utm:
__utma: contains a unique and anonymous identifying ID, which allows us to ensure that subsequent visits to our website are recorded as belonging to the same (unique) visitor. This cookie expires after two years.
__utmb: used to establish and continue a unique user session. Each time you request another page from the website the cookie is updated to expire after 30minutes.
__utmc: works with __utmb to determine when to create a new session for a website visitor. This is a session cookie and expires when you exit the browser.
__utmz: tracks how you found us and is used to calculate traffic and navigation within the website. It is updated with every new page view and expires after 6 months.
You may also sometimes find a __utmv cookie which relates to custom reporting segments, a feature which we occasionally use on Google Analytics.
