+  * “We collect data from web sites that place a link to our web servers on their web site. We call this link a beacon. (They are also known as an action tag, clear gif or tracking pixel). A beacon is designed to allow the site owner or a third party to monitor or collect information about a site visitor.” [Source](http://www.audiencescience.com/privacy/)
+  * “We also collect data from third party data providers, which may collect data from online and/or offline data sources, such as demographic, product purchase or registration information. For example, when a consumer signs up for a loyalty card at a retail store, the consumer may agree to allow the retailer to use the purchase data for marketing purposes. The retailer, or a third party they work with, will then repackage the purchasing data of many consumers in a way that it can be used for online marketing.” [Source](http://www.audiencescience.com/privacy/)
