What are some of these technologies?
Cookies are small files that are placed on your browser or device by the website or app you’re using or ad you’re viewing. Pixel tags (also called clear GIFs, web beacons, or pixels) are small blocks of code on a webpage or app that allow them to do things like read and place cookies and transmit information to us or our partners. The resulting connection can include information such as a device’s IP address, the time a person viewed the pixel, an identifier associated with the browser or device and the type of browser being used. Local storage is an industry-standard technology that allows a website or app to store and retrieve data on a person’s computer, mobile phone or other device. Some examples include device or HTML5 local storage and caching.
We use these technologies for a variety of reasons, such as allowing us to show you content and advertising that’s most relevant to you; improving our products and services; and helping to keep our Services secure.
