Tracking technologies, like cookies and web beacons, help websites and apps determine who you are and collect data about you.
You have choices regarding how or if
When you interact with us through our websites and apps, we use standard technologies that collect data about your behavior or how our products work. We also use those technologies when we communicate with you by email or text message. These technologies help us to optimize our products and services and give you a better experience. We want to help you understand what these tracking technologies are and what choices you have around them.
A cookie is a small data file that allows websites to recognize your browser or store information and/or settings. A website will send a small data file—or cookie—to your browser to first recognize it. Then it will store that information on your device.
Persistent cookies are stored on your device and used for various purposes by your browser on returning website visits—like to avoid having to re-enter your login information and saving your language preference. Session cookies are more temporary. They are stored in the browser for the duration of the browser session and are erased after you end a browser session or shut off your device.
You can change your cookie preferences in your browser settings. If you block cookies, some things on our website may not work properly.

A web beacon is an invisible digital object embedded in a webpage or email. Sometimes they can be called transparent or single pixel “GIFs.” Web beacons are used to monitor your interactions with that webpage or email—counting visitors, determining whether emails are opened, or monitoring how long a webpage was viewed.
Our webpages and emails may contain web beacons from our partners too, which help us compile statistics about the effectiveness of our marketing campaigns or assess website operations.
Mobile Advertising IDs, or “MAIDs,” are the way your device is uniquely identified for advertising purposes. These IDs are a random sequence of letters and numbers that are assigned to a mobile device. On Android devices, these IDs include AdID, and on Apple devices they include Identifier for Advertisers or IDFA.

Through our Privacy Dashboard, you can make choices about how we use your data—including whether we use your data to analyze your experiences and if you want to see ads that are more relevant to you. You can access and reset your ID or limit the use of it for targeted ads through the settings on your phone.
Analytics tools let us measure and understand how users interact with our websites, apps, and communications. These services are typically from third parties that we contract with—like Adobe and Google Analytics. These providers may use many of the same technologies explained above, like cookies and web beacons, to collect data around your visit to our websites and apps.
Most of the data these analytics partners collect does not directly identify you.
Depending on your device, you may have services that use the location of your device—like mapping or ride-sharing apps. These services are called location-based services (LBS) and are generally provided by third parties in connection with apps or websites. Third-party LBS providers will generally use your device’s location capabilities, which can determine your device location outside of our communications network.
You can change your location data permissions in your device’s system preferences or in-app settings. You can also uninstall apps that use location services. We recommend you familiarize yourself with the location capabilities and settings of your device and look into the privacy policies and terms where third-party LBS are provided.
