What are cookies?
Cookies are small pieces of information stored by a browser. Websites may also use local storage and similar technologies to maintain a session, remember preferences or support security.
Different storage mechanisms have different purposes and persistence periods.
Essential functionality
Some technical storage may be necessary for account sessions, navigation, fraud-prevention signals or other features requested by a visitor. Disabling such storage can cause parts of a site to work incorrectly.
Preferences and performance
Where implemented, preference storage can remember selected settings. Analytics technologies may be used to understand aggregate website performance or technical problems, subject to applicable privacy and consent requirements.
A technology should not be described as essential merely because it is convenient for marketing.
Third-party technologies
Embedded software, support services, media components and payment tools may have their own technical storage requirements and privacy policies.
Any actual third-party technology should be disclosed in a way that matches the deployed website.
Managing browser choices
Most browsers provide controls to view, delete or block cookies and other stored website data. Some browsers also provide tracking protection features.
Deleting essential session data may sign you out or reset preferences.
Personal data and enquiries
A cookie identifier can sometimes constitute personal data when it relates to an identifiable person. Relevant processing should follow the W9 Privacy Policy and applicable law.
