Last updated 01/01/2023. Interest-based ads are sometimes referred to as personalised or targeted ads. We show interest-based ads to display features, products, and services that might be of interest to you. What sort of information do we use to show interest-based ads? To serve you interest-based ads, we use information such as your interactions with the Zems sites, content, or services. We do not use personally identifiable information such as name or e-mail to serve interest-based ads. In serving you interest-based ads we only keep information collected for as long as required to provide our advertising services, in accordance with our Privacy Notice and applicable laws. As is common in the advertising industry, we use cookies, pixels, and other technologies (collectively, cookies), which enable us to understand the effectiveness of the interest-based ads we show you by measuring what ads are clicked or viewed, and to provide you with more useful and relevant ads. For example, if we know what ads are shown to your browser we can be careful not to show the same ads repeatedly. See our Privacy Notice for more information about the types of information that we gather. How do we work with third parties to show you interest-based ads? We work with third parties, such as advertisers, publishers, social media networks, search engines, ad serving companies, and advertising companies working on their behalf, to improve the relevance of ads we serve. In providing you interest-based ads we do not associate your interactions on unaffiliated sites with personally identifiable information, and we do not provide any personally identifiable information to advertisers or to third party sites that display our interest-based ads. Advertisers and other third parties may assume that users who interact with or click on an interest-based ad or content are part of the group that the ad or content is directed towards (for example, users in a particular geographical area or users who purchased or browsed for classical music). Some third-parties may provide us non-personally identifiable information about you (such as demographic information or sites where you have been shown ads) from offline and online sources that we may use to provide you with more relevant and useful advertising. Third party advertisers or advertising companies working on their behalf sometimes use cookies in the process of delivering content, including ads, directly to your browser or device, and they may automatically receive an IP address when this happens. They may also use cookies to measure the effectiveness of their ads, show you more relevant advertising content, and perform services on behalf of Zems. For information on how to control and delete cookies (including third party cookies) please visit our Cookies notice. Learn more about third parties that may set cookies when you use Zems services. Advertising Preferences Zems offers you choices about receiving interest-based ads from us. You can choose not to receive interest-based ads from Zems. You will still see ads, but they will not be based on your interests. Please visit your Advertising Preferences page to learn how to set your preferences.
