We (or our service providers) may use the information we collect, for instance, IP addresses and unique mobile device identifiers, to locate or try to locate the same unique users across multiple browsers or devices (such as smartphones, tablets, or computers), or work with providers that do this, in order to better tailor content and features and provide you with a seamless experience across devices. If you wish to opt out of such cross device tracking for purposes of interest-based advertising, you may do so through your device settings. We may also use cross-device tracking to help identify our users and serve advertising.
