MU Wiki:Privacy Policy

Privacy policy From the MU Wiki Foundation

General Scope

This policy covers personally identifiable information collected or stored by the Foundation on its servers in relation to the Projects and their communities. Consistent with its Data Retention Policy, the Foundation collects and retains the least amount of personally identifiable information needed to fulfill the Projects' operational needs. The public and collaborative nature of the projects

All Projects of the Wikimedia Foundation are collaboratively developed by its users using the MediaWiki software. Anyone with Internet access (and not otherwise restricted from doing so) may edit the publicly editable pages of these sites with or without logging in as a registered user. By doing this, editors create a published document, and a public record of every word added, subtracted, or changed. This is a public act, and editors are identified publicly as the author of such changes. All contributions made to a Project, and all publicly available information about those contributions, are irrevocably licensed and may be freely copied, quoted, reused and adapted by third parties with few restrictions. Activities on Foundation projects

In general, this Policy only applies to private information stored or held by the Foundation which is not publicly available.

Interactions with the Projects not covered by this Policy include, but are not limited to, aspects of browsing and editing pages, use of the wiki "email user" function, subscribing and posting to Foundation hosted email lists, and corresponding with volunteers via the Foundation's ticketing system ("OTRS"). These interactions may reveal a contributor's IP address, and possibly other personal information, indiscriminately to the general public, or to specific groups of volunteers acting independently of the Foundation.

Users may also interact with one another outside of Foundation sites, via email, IRC or other chat, or independent websites, and should assess the risks involved, and their personal need for privacy, before using these methods of communication. User accounts and authorship

The Foundation does not require editors to register with a project. Anyone can edit without logging in with a username, in which case they will be identified by network IP address. Users that do register are identified by their chosen username. Users select a password, which is confidential and used to verify the integrity of their account. Except insofar as it may be required by law, no person should disclose, or knowingly expose, either user passwords and/or cookies generated to identify a user. Once created, user accounts will not be removed. It may be possible for a username to be changed, depending on the policies of individual projects. The Foundation does not guarantee that a username will be changed on request. Purpose of the collection of private information

The Foundation limits the collection of personally identifiable user data to purposes which serve the well-being of its projects, including but not limited to the following:

To enhance the public accountability of the projects. The Foundation recognizes that any system that is open enough to allow the greatest possible participation of the general public will also be vulnerable to certain kinds of abuse and counterproductive behavior. The Foundation and the project communities have established a number of mechanisms to prevent or remedy abusive activities. For example, when investigating abuse on a project, including the suspected use of malicious “sockpuppets” (duplicate accounts), vandalism, harassment of other users, or disruptive behavior, the IP addresses of users (derived either from those logs or from records in the database) may be used to identify the source(s) of the abusive behavior. This information may be shared by users with administrative authority who are charged by their communities with protecting the projects.

To provide site statistics. The Foundation statistically samples raw log data from users' visits. These logs are used to produce the site statistics pages; the raw log data is not made public.

To solve technical problems. Log data may be examined by developers in the course of solving technical problems and in tracking down badly-behaved web spiders that overwhelm the site.

Details of data retention General expectations

IP and other technical information

When a visitor requests or reads a page, or sends email to a Wikimedia server, no more information is collected than is typically collected by web sites. The Wikimedia Foundation may keep raw logs of such transactions, but these will not be published or used to track legitimate users.

When a page is edited by a logged-in editor, the server confidentially stores related IP information for a limited period of time. This information is automatically deleted after a set period. For editors who do not log in, the IP address used is publicly and permanently credited as the author of the edit. It may be possible for a third party to identify the author from this IP address in conjunction with other information available. Logging in with a registered username allows for better preservation of privacy.

Cookies

The sites set a temporary session cookie on a visitor's computer whenever a Project page is visited. Readers who do not intend to log in or edit may deny this cookie; it will be deleted at the end of the browser's session. More cookies may be set when one logs in to maintain logged-in status. If one saves a user name or password in one's browser, that information will be saved for up to 30 days, and this information will be resent to the server on every visit to the same Project. Contributors using a public machine who do not wish to show their username to future users of the machine should clear these cookies after use.

Page history

Edits or other contributions to a Project on its articles, user pages and talk pages are generally retained forever. Removing text from a project does not permanently delete it. Normally, in projects, anyone can look at a previous version of an article and see what was there. Even if an article is "deleted", a user entrusted with higher level of access may still see what was removed from public view. Information can be permanently deleted by individuals with access to Wikimedia servers, but aside from the rare circumstance when the Foundation is required to delete editing-history material in response to a court order or equivalent legal process, there is no guarantee any permanent deletion will happen.

User contribution

User contributions are also aggregated and publicly available. User contributions are aggregated according to their registration and login status. Data on user contributions, such as the times at which users edited and the number of edits they have made, are publicly available via user contributions lists, and in aggregated forms published by other users.

Reading projects

No more information on users and other visitors reading pages is collected than is typically collected in server logs by web sites. Aside from the above raw log data collected for general purposes, page visits do not expose a visitor's identity publicly. Sampled raw log data may include the IP address of any user, but it is not reproduced publicly.

Editing projects

Edits to Project pages are identified with the username or network IP address of the editor, and editing history is aggregated by author in a contribution list. Such information will be available permanently on the projects.

Logged in registered users:

Logged in users do not expose their IP address to the public except in cases of abuse, including vandalism of a wiki page by the user or by another user with the same IP address. A user's IP address is stored on the wiki servers for a period of time, during which it can be seen by server administrators and by users who have been granted CheckUser access.

IP address information, and its connection to any usernames that share it, may be released under certain circumstances (see below).

Editors using a company mail server from home or telecommuting over a DSL or cable Internet connection, are likely to be easy to identify by their IP address; in which case it may be easy to cross-identify all contributions to various Projects made by that IP. Using a username is a better way of preserving privacy in this situation.

Unlogged-in registered users and unregistered users:

Editors who have not logged in may be identified by network IP address. Depending on one's connection, this IP address may be traceable to a large Internet service provider or more specifically to a school, place of business or home. It may be possible to use this information in combination with other information, including editing style and preferences, to identify an author completely.

Disclaimer

The MU Wiki Foundation believes that maintaining and preserving the privacy of user data is an important value. This Privacy Policy, together with other policies, resolutions, and actions by the Foundation, represents a committed effort to safeguard the security of the limited user information that is collected and retained on our servers. Nevertheless, the Foundation cannot guarantee that user information will remain private. We acknowledge that, in spite of our committed effort to protect private user information, determined individuals may still develop data-mining and other methods to uncover such information and disclose it. For this reason, the Foundation can make no guarantee against unauthorized access to information provided in the course of participating in Foundation Projects or related communities
