For more information, see our Privacy Policy.


For the purposes of these guidelines:

  • "Personal information" means information you provide us or information we collect from you that identifies or could be used to personally identify you. For details, please see the Wikimedia Foundation Privacy Policy and Non-Wiki Privacy Policy.
  • Some examples of "public information" would include:
    • (a) your IP address, if you edit without logging in;
    • (b) your gender, if it is disclosed under your user profile;
    • (c) any personal information you disclose publicly on the Wikimedia Sites, such as your real name or age.
  • Some examples of types of information that are considered to be "nonpublic information" include:
    • (a) your IP address, if you edit while logged in;
    • (b) your email address, if you provided one to us during account registration (but didn’t post it publicly); and
    • (c) your general location information as might be derived from your IP address, if you have not posted it publicly. The types of information that are considered "nonpublic" as opposed to "public" are more fully explained in our Privacy Policy.
  • Data is "de-identified" when it has been aggregated or otherwise retained in a manner such that it can no longer be used to identify the user.
  • Data is "aggregated" when the data associated with a specific user has been combined with data from others to show general trends or values without identifying specific users.


Using ranges rather than specific numbers, such as recording that there are "between 1 and 10 editors in language X in country Y" rather than recording that there are 4 editors.

Terms that are not defined in this document have the same meaning given to them in the Privacy Policy.


If we make exceptions to these guidelines, we will notify the community by describing the exception on this page.

  • 数据也许会在系统备份中保留更长周期,但最多不会超过5年。
  • When we conduct a survey or other research, we will provide you with a privacy statement specifying the term of retention for information (including personal information) collected through your participation in such research. In certain cases, information may be retained indefinitely for educational, development, or other related purposes, unless otherwise indicated in the relevant privacy statement. Such information may be retained in raw, aggregated, or de-identified form until we receive a request from the participant to delete the information.
  • Research related to COVID-19: The Wikimedia Foundation Research team is conducting research regarding COVID-19 and its impact on Wikipedia. Retaining de-identified readership data from COVID-19 related articles will enable us to better understand how to prioritize content creation, to understand what happens to readership when there's a "shock to the system", and to empower the research community to answer such questions. By "COVID-19 related articles", we mean articles that link to the COVID-19, SARS-CoV-2 and 2019–20 COVID-19 pandemic Wikidata items. For comparison purposes, we will retain data from a small number of articles unrelated to COVID-19 as well. In order to collect sufficient data, and obtain a picture of readership as time passes, we will be retaining this de-identified data beyond the 90-day retention limit, for a period of one year, ending on March 1, 2021. (Note that this includes a one-month extension due to staffing changes, in order to allow for the project’s completion.). For technical details about the sampling and de-identification process, please see the project page on GitHub.
  • Editing research: There is a short-term extension applying to data collected as part of experimental features to improve replying on talk pages. In order to collect and analyze sufficient data, this data must be kept beyond the standard 90-day period. The retained data will be deleted, aggregated, or de-identified within 180 days.
  • In rare cases, we, or particular users with certain administrative rights as described in our Privacy Policy, may need to retain your personal information, including your IP address and user agent information, for as long as reasonably necessary (which may be longer than the period described in the table above) to:
    • enforce or investigate potential violations of our Terms of Use, this Privacy Policy, or any Foundation or user community-based policies;
    • investigate and defend ourselves against legal threats or actions;
    • help protect against vandalism and abuse, fight harassment of other users, and generally try to minimize disruptive behavior on the Wikimedia Sites;
    • prevent imminent and serious bodily harm or death to a person, or to protect our organization, employees, contractors, users, or the public; or
    • detect, prevent, or otherwise assess and address potential spam, malware, fraud, abuse, unlawful activity, and security or technical concerns.

Audits and improvements

The Foundation is committed to continuous evaluation and improvement of these guidelines, and to periodic audits in order to identify such improvements. As we make changes to existing and systems, we will update these guidelines to reflect our changing practices.


In order to support these data retention periods and our overall privacy policy, new tools and systems implemented by the Foundation will be designed with privacy in mind. This will include:

  • inclusion of these data retention guidelines as requirements during the design process;
  • legal consultation during the design and development process; and
  • inclusion of privacy considerations in the code review process.


Despite our best efforts in designing and deploying new systems, we may occasionally record personal information in a way that does not comply with these guidelines. When we discover such an oversight, we will promptly comply with the guidelines by deleting, aggregating, or de-identifying the information as appropriate.


If you think that these guidelines have potentially been breached, or if you have questions or comments about compliance with the guidelines, please contact us at privacy(_AT_)wikimedia.org.
