Because we believe that you shouldn’t have to provide personal information to participate in the free knowledge movement, you may:
If you add content or make a change to a Wikimedia Site without logging in, that content or change will be publicly and permanently attributed to the IP address used at the time rather than a username.
Our community of volunteer editors and contributors is a self-policing body. Certain administrators of the Wikimedia Sites, who are chosen by the community, use tools that grant them limited access to nonpublic information about recent contributions so they may protect the Wikimedia Sites and enforce policies.
As part of our commitment to education and research around the world, we occasionally release public information and aggregated or non-personal information to the general public through data dumps and data sets.
