Effective Date: May 25th, 2018

Sovrn Holdings, Inc. (“Sovrn”) provides this privacy policy (“Privacy Policy”) to describe ours and our subsidiaries information practices for our Publishers and Readers.
By using the Sovrn Services or submitting Personal Information through our Sovrn Services, you acknowledge and agree to the terms of this Privacy Policy and to the processing of your Personal Information in accordance with this Privacy Policy.

What This Privacy Policy Covers
Through the Sovrn Services including the website, the Sovrn publisher platform and other Sovrn publisher tools and widgets, the Sovrn ad exchange, Sovrn header bidding, Sovrn video products, Sovrn analytics and data services, and other Sovrn products and services (together the “Sovrn Services”), we collect information about Publishers and Readers. “Publishers” are websites or publications where Sovrn Services reside, or natural persons who interact with Sovrn on behalf of such websites or publications. “Readers” are individuals who visit our Publishers’ websites. We use and disclose information collected from or about our Publishers and Readers as described in this Privacy Policy.

This Privacy Policy describes Sovrn’s use of Personal Information and Other Information that we collect when you use the Sovrn Services. “Personal Information” means any information that can be used to directly or indirectly identify a natural person, such as contact information (i.e., name, address, e-mail address, and/or phone number), any other data that is associated with the contact information, and/or information that identifies a browser or device such as an IP address, advertising identifier, cookie identifier, or email address that has been hashed to generate an alphanumeric identifier, or combination of information about a browser or device (such as IP address and browser type/settings). “Other Information” means information that is not associated with or linked to your Personal Information including aggregate or de-identified information. We collect and use Personal Information and Other Information as described in this Privacy Policy from both Publishers and Readers.

The Sovrn Services contain links to websites or content, including advertisements, operated and maintained by third parties, over which we have no control. We encourage you to review the privacy policy of a third-party website before disclosing any information to the website.

Information You Provide to Us

The Personal Information we gather from our Publishers and Readers helps us provide the Sovrn Services and learn more about how our Publishers and Readers use Sovrn Services. We collect the following Personal Information that our Publishers and Readers submit to us voluntarily:

Information from Publishers: Our Publisher registration process requires a valid email address and a username and password, among other information. We may also request optional information to support use of the Sovrn Services, such as the first and last name, bio, year of birth, zip code, and country of residence for the Publisher contact. We may collect information about the categories of content our Publishers typically make available to others on pages integrated with Sovrn Services and link this information to Personal Information provided for that account. For example, we categorize the types of content that Publishers make available. We collect payment information from Publishers who purchase Sovrn Services, including by participating in our advertising services. A Publisher may also choose to provide us with log-in credentials for accounts with third-party services such as online advertising providers, in order for Sovrn to provide services, such as reporting, based on information from those third-party services.

Information from Publishers and Readers: You may choose to provide us with other Personal Information. For example, if you sign up for a ‘Sovrn Alert’ or newsletter, we collect your email address. When you contact us by sending us an email or providing other feedback, we will collect any information that is contained in your email or feedback.

You can choose not to provide us with certain Personal Information, but this may limit the features of the Sovrn Services you are able to use.

Information Collected Via Technology

Interest-Based Advertising and Opting Out
For our legitimate business interests, and with your consent where this is required, we may process and disclose your Personal Information for interest-based advertising as described in this section.

Opting Out of Sovrn’s Activities: Sovrn collects, uses, and discloses web viewing data, app usage data, and precise location data across non-affiliated sites and apps over time for the purpose of delivering interest-based advertising to this device or different devices. We make available a Sovrn “opt-out” cookie that you may download to your browser. If this cookie is installed on your browser, we will not collect, use, or transfer such data from or on that browser for the purpose of interest-based advertising. You can visit to learn more about interest-based advertising and to exercise your opt-out choice with respect to Sovrn and other companies participating in the Digital Advertising Alliance (DAA) self-regulatory program.

If you wish to opt-out of Sovrn’s collection, use, or transfer of such data from your mobile device for interest-based advertising purposes, you can download the DAA’s AppChoices app from your device’s application store. If you opt out through AppChoices, we will not collect, use or transfer such data from or on that device for interest-based advertising.

When you use the opt-out tools above, your choice will be effective only on the browser or device where you exercised the choice. If you use a different device or browser, you will need to renew your opt-out choice. Our opt-out tool for browsers is cookie-based. It will be installed only if your browser is set to accept third-party cookies, and if you delete this cookie then you will need to renew your opt-out choice. Even if you opt out on your browser or your mobile device, we may continue to collect, use and transfer such data for other purposes such as contextual advertising based on a current visit to a website, fraud prevention, improving site performance and other purposes referred to in this Privacy Policy.

Opting out will not stop advertising from appearing in your browser. Even if you opt out, you still may receive advertising from the Sovrn Services when you visit websites of a Publisher who uses our Services, but that advertising will not be targeted to you. If you opt out of Sovrn’s practices, you may also continue to receive interest-based advertising through other companies.

Opting Out of Third-Party Activities: We enable third-party partners to collect web viewing data on the Sovrn Services and across unrelated websites and online services for purposes that include “interest-based advertising,” which is the process of showing you targeted ads on one or more devices that are more likely to be relevant to you based on inferences drawn from your Web viewing data collected across non-affiliated sites over time and across browsers and devices. These third-party partners that participate in the Sovrn Services may also use their own cookies and other ad service technologies to display and track their ads. To opt out of this type of advertising from companies participating in the Digital Advertising Alliance or European Digital Advertising Alliance self-regulatory programs, you can visit (for U.S. residents) or We will send you messages related to our relationship (such as, but not limited to, service messages, invoices and notices of any updates to our Publisher Agreement or Privacy Policy) when it is necessary to do so. You may not opt-out of these communications, but if you do not wish to receive these announcements, you have the option to deactivate your account as discussed below.

Please see above for information on opting out of Sovrn’s collection, use and transfer of data for interest-based advertising purposes.

You may be entitled to ask us for a copy of your Personal Information, to correct it, erase or restrict its processing, or to ask us to transfer some of this information to other organizations. As further detailed in other sections of this Privacy Policy, you also have rights to object to some processing, such as profiling we perform for the purposes of direct marketing and interest-based advertisement, and, where we have asked for your consent to process your data, to withdraw this consent. In some cases, you can exercise these rights through automated means. Where this is not possible you can contact us through our web form or through the contact details provided under the “Contact Us” section later in this Privacy Policy. These rights may be limited in some situations – for example, where we can demonstrate that we have a legal requirement to process your data. In some instances, this may mean that we are able to retain data even if you withdraw your consent.

Where we require Personal Information to comply with legal or contractual obligations, then provision of such data is mandatory: if such data is not provided, then we will not be able to manage our contractual relationship, or to meet obligations placed on us. In all other cases, provision of requested Personal Information is optional.

Cross-border Transfer of Personal Information
Your Personal Information may be processed by us in the country where it was collected as well as other countries (including the United States) where laws regarding processing of Personal Information may be less stringent than the laws in your country.

Where Personal Information is transferred outside of the EEA to a data importer in a country that is not subject to an adequacy decision by the EU Commission, data is adequately protected by an appropriate safeguard such as approved standard contractual clauses (by the EU Commission, the European Data Protection Supervisor or a competent authority).
