4. Cookies and Other Technologies.

   This section describes the types of tracking technologies we use to automatically collect information from your browser or device. See Your Privacy Choices to exercise choice around tracking technologies.

   • Cookies. Cookies are browser-based text files placed on your browser when you visit a website, or open or click on an email. There are various types of cookies, including session cookies (which expire when you close your browser) and persistent cookies (which remain until a set expiration date or until you manually delete them). Cookies may be first party (served directly by us) or third party (served by third parties we work with).
   • Pixels. Pixels (also known as web beacons) are pieces of code embedded in a service. There are various types of pixels, including image pixels (typically one-pixel transparent images) and JavaScript pixels (which execute code). Pixels are often used in conjunction with cookies. When you access a service that contains a pixel, the pixel may allow us or a third party to collect information from your browser or device, or to place or read cookies on your browser.

   We use these tracking technologies for various purposes, including to operate our Service, personalize your browsing experience, prevent fraud, improve security, perform measurement and analytics, and provide advertising.

   In addition, with your consent we may access additional technologies on your device:

5. Purposes for Collection and Use.

   We collect and use information for the following purposes:

   • To provide services, including operating and maintaining the Service.
   • To personalize your experience, including showing you content we believe may be of interest to you.
   • To communicate with you, including sending transactional and marketing messages by email.
   • To understand usage and trends, including through surveys you respond to and tracking technologies incorporated into the Service (such as Google Analytics).
   • To improve products and services.
   • To administer promotions. If you enter a promotion, you agree to the official rules, which may allow us, the sponsor, or related parties to use your information as described in this Privacy Policy. Where permitted by law, this includes us using your name, voice, or likeness in advertising or marketing materials.
   • For security, compliance, and enforcement, including preventing, detecting, investigating, and responding to fraud, misuse, policy or legal violations, or threats to safety.
   • At your direction, including where you instruct us to use your information in a specific way or where we notify you and obtain your consent.
   • Non-personal information. We may anonymize or deidentify information so it is no longer considered personal information under applicable law. Where we deidentify information, we commit to maintaining and using the deidentified information in deidentified form and not attempt to reidentify it. We may use non-personal information for any purpose permitted by law.

   See Your Privacy Choices to exercise choice around our collection and use.

Service providers perform services for us, such as payment processing, data analytics, marketing and advertising, website hosting, and technical support. To the extent required by law, we contractually prohibit our service providers from processing information they collect on our behalf for purposes other than performing services for us, although we may permit them to use non-personal information for any purpose permitted by law.

   • Recipients for legal, security, and enforcement purposes. We disclose information to comply with the law or other legal process, and where required, in response to lawful requests by public authorities, including to meet national security or law enforcement requirements. We also disclose information to protect the rights, property, life, health, security, and safety of us, the Service, or anyone else.
