We may also work with a number of companies that assist in marketing our services to you on third party websites, mobile apps, and online services. These third parties may use cookies, web beacons or other tracking technologies to collect information about your use of the Services and your activities across other websites and online services, which they may associate with persistent identifiers. Sometimes, these identifiers may be derived from a hashed or encrypted version of personal information such as your email address. We may use this information to measure the performance of our advertising as well, for instance, to evaluate which ads or content our users prefer, or which are most effective. In addition, sometimes we or an advertising partner may tailor advertising to you across different devices.</p> <p>
