Much of GitHub is public-facing. If your content is public-facing, third parties may access and use it in compliance with our Terms of Service, such as by viewing your profile or repositories or pulling data via our API. We do not sell that content; it is yours. However, we do allow third parties, such as research organizations or archives, to compile public-facing GitHub information. Other third parties, such as data brokers, have been known to scrape GitHub and compile data as well.

Your Personal Information, associated with your content, could be gathered by third parties in these compilations of GitHub data. If you do not want your Personal Information to appear in third parties’ compilations of GitHub data, please do not make your Personal Information publicly available and be sure to configure your email address to be private in your user profile and in your git commit settings. We currently set users' email address private by default, but legacy GitHub users may need to update their settings.

If you would like to compile GitHub data, you must comply with our Terms of Service regarding scraping and privacy, and you may only use any public-facing Personal Information you gather for the purpose for which our user has authorized it. For example, where a GitHub user has made an email address public-facing for the purpose of identification and attribution, do not use that email address for commercial advertising. We expect you to reasonably secure any Personal Information you have gathered from GitHub, and to respond promptly to complaints, removal requests, and "do not contact" requests from GitHub or GitHub users.
