Other third parties, account connections, and integrations. We may receive information about you from third parties who are not our ad partners, such as other X users, developers, and partners who help us evaluate the safety and quality of content on our platform, our corporate affiliates , and other services you link to your X account. You may choose to connect your X account to your account on another service, and that other service may send us information about your account on that service.

Breaking down how we use the information we collect is not simple because of the way the systems that bring our services to you work. For example, the same piece of information may be used differently for different purposes to ultimately deliver a single service. We think it's most useful to describe the five main ways we use information and if you have questions that are not answered, you can always contact us . Here we go:

2.1 Operate, improve, and personalize our services.

We use the information we collect to provide and operate X products and services. We also use the information we collect to improve and personalize our products and services so that you have a better experience on X, including by showing you more relevant content and ads, suggesting people and topics to follow, enabling and helping you discover affiliates , third-party apps, and services. We may use the information we collect and publicly available information to help train our machine learning or artificial intelligence models for the purposes outlined in this policy. We may use the information we collect from accounts of other services that you choose to connect to your X account to provide you features like cross-posting or cross-service authentication, and to operate our services.

We use your contact information to help others find your account if your settings permit, including through third-party services and client applications.

We use your information to provide our advertising and sponsored content services subject to your settings , which helps make ads on X more relevant to you. We also use this information to measure the effectiveness of ads and to help recognize your devices to serve you ads on and off of X. Some of our ad partners also enable us to collect similar information directly from their website or app by integrating our advertising technology. Information shared by ad partners and affiliates or collected by X from the websites and apps of ad partners and affiliates may be combined with the other information you share with X and that X receives, generates, or infers about you, as described elsewhere in our Privacy Policy.
