Company Link to DNT Policy Policy Language

“Some new browsers have a ‘do-not-track’ feature. When this feature is turned on, Acxiom treats this as if you had opted out of our online advertising products.”

Baycloud

“We use local storage in your browser to record which sites you haven given consent to. This data is stored entirely within your browser and not transmitted to our servers. We do not store or use any unique identifiers in cookies or anywhere else, and do not track or target you in any way. . . . If you have explicitly given your consent for tracking for a particular web site or server we may set your browser’s Do Not Track header to indicate this, if your browser supports this capability.”

BlueCava

“… users can either opt out or set their preferences when it comes to online marketing. There’s a difference between being identified and being tracked: if you turn tracking off, we can still identify a device but we don’t keep track of which websites it’s been to.

“Our Technology is designed to recognize a Do Not Track (DNT) signal, but we do not control how our Clients respond to DNT signals.’

“Chitika collects information about consumers’ activities on certain websites in order to deliver targeted advertisements. By opting out [via DNT], Chitikawill not collect this information for the purpose of delivering targeted advertisements.”

“If you consent, your location and Device Identifier will be used so that we can, together with our advertisers, provide content and advertising which is relevant to both you and your location (called “Personalised Advertising”) . . . You can unsubscribe from these user and location based services or withdraw your consent to receiving Personalised Advertising at any time by setting the ‘Do Not Track’ preference in your browser.”

Effective Measure

“Effective Measure, the leading provider of digital media planning solutions in emerging markets, has announced that it is the first of its kind to promote greater transparency by enabling the ‘Do Not Track’ browser option should users choose to opt out.”

Healthcare.gov

“[Centers for Medicare & Medicaid Services] automatically observes the “Do Not Track” browser setting for digital advertising that uses “conversion-tracking” or “re-targeting”. If “Do Not Track” is set before a device visits HealthCare.gov, third party conversion tracking and retargeting tools will not load on the site.”

Hulu

“Hulu supports “Do Not Track” browser settings. If you enable Do Not Track settings in the browser you are using, Hulu will not use information about websites you visit (other than the Hulu Site) using that browser.”

Krux

“Currently, the standards regarding the DNT signals and appropriate responses are not defined.  As a result, Krux is experimenting with DNT and may place an opt-out cookie on computers or other devices when we see a valid DNT signal.”

Medium

We respect Do Not Track (“DNT”) settings in browsers. If you’re logged out of our Services and have DNT enabled, we will not set cookies. By logging in you are opting to allow Medium to ignore the DNT setting and to use cookies in order to provide you a personalized experience.”

“[W]e support the Do Not Track browser setting . . .”

Reddit

“Do Not Track (“DNT”) is a privacy preference that you can set in most web browsers. We support DNT in our Services. There is no accepted standard on how to respond to web browsers’ DNT signals. When you have DNT enabled, we may still use information collected for analytics and measurement purposes or to otherwise provide our Services (e.g., reddit.com buttons), but we will not load any third-party trackers.”

Twitter

For tailored suggestions: If you do not want Twitter to tailor suggestions for you based on your visits to websites that have integrated Twitter buttons or widgets, you can turn off this feature for a given browser using your Do Not Track browser setting.

For tailored ads: If you do not want Twitter to match your account to browser-related information to tailor ads for you, you can turn off this feature for a given browser using your Do Not Track browser setting,

If you do not want our [third-party] advertising providers to use your visits to Twitter websites to show you personalized ads, you can opt out using your Do Not Track browser setting.

When you have DNT enabled, we may still use information about website visits for analytics and measurement purposes . . .”
