We may share with these third parties (or they may directly collect) data such as cookie and mobile ad identifiers in order to engage in advertising activity (including to understand how you respond to advertisements and to serve relevant ads). Twitch also works with third parties to serve ads to you off Twitch’s Services. When we do so, we may share information such as your email address or resettable device identifier for that advertising partner to “match” to other information that may have about you.</p> <p>Advertisers on Twitch, or representatives or service providers working on their behalf (“Twitch Advertisers”), sometimes use technology to serve ads that appear on our services directly to your device.&nbsp. They automatically receive certain data, such as your IP address, when this happens. They may also use cookies (or similar technologies) to measure the effectiveness of their ads and to personalize ad content.
