Twitter updated its privacy policy and terms of service late last week.

Besides offering new features, such as a weekly digest email, additional languages, and Do Not Track option for Mozilla users, the microblogging site also clarified what user data it collects.

Twitter saves all public data, which includes profile information as well as all your tweets, who you follow, your lists, “and many other bits of information that result from your use of the Services.”

For 18 months, Twitter also stores its users  IP address, browser type, operating system, referring Web pages, pages visited, location, mobile carrier, device and application IDs, search terms, and cookie information.

Twitter will only share data the user gives it permission to share or in special circumstances, such as “Law and Harm.” As Twitter explained:

“[W]e may preserve or disclose your information if we believe that it is reasonably necessary to comply with a law, regulation or legal request; to protect the safety of any person; to address fraud, security or technical issues; or to protect Twitter's rights or property.”

The microblogging platform alerted some users to the alterations over the weekend. Here’s a look at how the community responded to the announcement.
