Privacy Policy and Opt-Out Guide


Krux delivers technology to help website operators and users manage and protect consumer data. Our overarching goal is to make digital media less creepy and more productive for consumers, publishers, and advertisers. That's why we take data privacy and data piracy very seriously.

There are many practices on the web today that, while not illegal, are unethical and inappropriate. Two of the more egregious examples include the distribution of spyware or malware, and the emerging practice of reaching into a user's browser during a website visit to read and record past web surfing habits. Serious questions can also be raised about the increasing number of third parties who are skimming or stealing audience data from a website through rogue cookie and pixel activities.

We make Publishers (defined below) and other website operators aware of uninvited, unauthorized entities who are skimming data from their sites, and we give them tools to mitigate and control such data flow within the technical limitations induced by existing internet protocols and standards.

We use data collected via our technology to enhance our products, improve the performance and security of our systems and our customer’s systems, and support our customers' business needs within the bounds established by this privacy framework. Krux is not in the business of setting industry standards, but we do all that we can to advance industry dialogue and improve standards of practice. To that end we will enable our clients to manage their data in a responsible way; we will empower consumers to determine what data is collected and how it is used; and we will expose inappropriate or unethical practices in data collection and ad targeting whenever we discover them. Through our technology, we will expose bad actors and their actions, educating the industry and consumers on the impact of any unethical, inappropriate, or illegal activities we discover.

In all of our work, we will seek to maintain alignment with standards established by groups such as the IAB, NAI, DAA, and OPA, and we are members in good standing of the IAB and OPA. When we feel industry standards fall short, we will take all reasonable steps to ensure that our customers and consumers receive greater protection. Above all, our priorities are to advance the interests of publishers and consumers and to expose and correct bad data practices. By doing so, we will enable the industry to become a more responsible steward of audience data.

Data Collection on the Internet

Users have the ability to accept or decline cookies. Currently, there are five ways to disable or delete the cookies stored by your Internet browser. Each browser is different in its user interface, so you may need to refer to your help or FAQ file to determine how to delete or disable cookies in your browser. You may set the browser to:

  1. delete all cookies manually
  2. refuse all cookies for all website visits
  3. refuse all third party cookies (all cookies from other than the website being visited)
  4. use an "Opt-Out" mechanism;
  5. require your approval to accept cookies.

If you delete or refuse cookies you will find that many websites do not function as well as they did when using cookies. For example, websites where you have an account may not recognize your browser and it may take additional steps to login and reach the desired portion of the website. If you require permission to accept cookies, you may find the number of requests is so high as to make this impractical. If you accept cookies, you will be able to later delete the cookies. Please refer to information provided by your browser and follow the instructions regarding deleting cookies.

Current web browsers that conform with industry standards contain a mechanism, known as a "Do Not Track" ("DNT"), that allows a user to elect to opt-out of the collection of certain browsing data by websites. As a user, you may elect to employ the DNT option if your browser supports it. The Krux platform recognizes these DNT signals from consumer browsers and ensures those users' wishes are honored across all websites using our technology for data collection and targeting. Further, Krux offers a one click opt-out solution for users who have not made a DNT election but who wish to opt-out of any tracking and targeting via Krux.

Implementation Options

Krux has a standard Opt-out URL that can be called by our partners to execute the opt-out action for a user. A user can opt-out of tracking by the Krux platform by visiting and clicking on the "Opt-out" button.

Krux Opt-Out is the standard Krux opt-out URL. When called directly, this URL will execute the Opt-out action for a user and it will return the following JSON response:


A user must allow cookies from Krux in order to opt-out. Calling the Krux opt-out code (by clicking on an opt-out button placed on the client's page) will result in a persistent 'cookie' placed in the user’s web browser by Krux, identifying that user as being on the Krux 'do not target' list. Taking this opt-out step won't prevent all tracking and targeting online, but it will ensure the user’s wishes are honored by participating Krux publishers.

Note: If the user uses more than one computer, the process must be repeated for each one as this information is associated with a cookie unique to each machine.

Krux Cookie Status

To determine the tracking state of a user (opted-out vs. opted-in), a publisher should call This will return one of the following JSON responses:

{"code": "optedout"}

if the user has opted out of tracking by Krux

{"code": "optedin"}

if the user is opted-in to tracking by Krux
