On both Amazon-owned and operated sites and unaffiliated sites, Amazon displays interest-based advertising using information you make available to us when you interact with our sites, content, or services. Interest-based ads, also sometimes referred to as personalized or targeted ads, are displayed to you based on information from activities such as purchasing on our sites, visiting sites that contain Amazon content or ads, interacting with Amazon tools, or using our payment services, like Checkout by Amazon. Click here for more information about the types of information that we gather. In providing interest-based ads, we follow the Self-Regulatory Principles for Online Behavioral Advertising developed by the Digital Advertising Alliance (a coalition of marketing, online advertising, and consumer advocacy organizations).
We do not provide any personal information to advertisers or to third party sites that display our interest-based ads. However, advertisers and other third-parties (including the ad networks, ad-serving companies, and other service providers they may use) may assume that users who interact with or click on a personalized ad or content are part of the group that the ad or content is directed towards (for example, users in the Pacific Northwest who bought or browsed for classical music). Also, some third-parties may provide us information about you (such as the sites where you have been shown ads or demographic information) from offline and online sources that we may use to provide you more relevant and useful advertising.
