Opti Digital does not set any cookies without your consent. The following table contains cookie or local storage values set by the Opti Digital advertising service on Opti Digital-operated domain names when the User has accepted cookies.

Opti Digital provides an advertising technology that allows websites, apps and other internet-connected properties to generate revenue by showing advertisements to their users, and allows marketers and other advertisers to show advertisements to individuals online who may be interested in their products or services. Opti Digital Ad Marketplace is designed to use information on Internet users that cannot identify them “in the real world.” Opti Digital has contractual provisions that prohibit clients of the Opti Digital Ad Marketplace from directly associating Opti Digital cookies with any personal information that directly identifies an individual.

A cookie is a small bit of information that is sent to and stored in a browser by a website you visit or by that website’s service partners. They are used to store and receive identifiers and other information on computers, phones and other devices. By saving information in a cookie, websites can remember preferences or recognize browsers from one visit to another or from one website to another. 

Only the site or service that places a particular cookie can read the contents of that cookie each time it communicates with your browser. Other technologies, including data we store on your web browser or device and identifiers associated with your device are used for similar purposes. In this policy, we refer to all of these technologies as “cookies.”

Below you will find information on Opti Digital cookies, all of which are set on the domain. Except as noted in the table below, all of these cookies are set by Opti Digital Ad Marketplace.

Certain of the cookies we use last only for the duration of your internet session and expire when you close your browser. Other cookies are used to remember you when you return to a website and will last for longer. Opti Digital Ad Marketplace uses cookies to associate information that does not directly identify an individual with browsers and devices, so that Opti Digital Ad Marketplace and our clients can then use the information to select ads for delivery by Opti Digital Ad Marketplace. For a detailed privacy statement that applies to Opti Digital and describes how we collect and use information, and information about how we use technologies other than cookies, see our Privacy Policy.

Note: Most web and mobile device browsers automatically accept cookies but, if you prefer, you can change your browser to prevent that or to notify you each time a cookie is set.  You can also learn more about cookies by visiting which includes additional useful information on cookies and how to block cookies using different types of browser or mobile device.
