• "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 .

• 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.

?据如何聚合的例子：

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.

方?例外情?

• ?据也??在系???中保留更?周期，但最多不?超?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 is 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 2019-2020 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.
• Campaign landing pages: for certain events, campaigns, or marketing channels, users may create accounts on special landing pages. After creating their account on those pages, the association between their account and its source may be retained indefinitely, both to provide a good user experience for that account and for longitudinal analysis on campaign effectiveness. For more information, contact mmiller wikimedia.org.
• CampaignEvents extension: An exception exists for data collected by the CampaignEvents extension . The extension collects the global user IDs of event organizers and event participants, as well as which events users organized or attended and when participants registered for an event. In order for the extension features to work consistently, data collected by the CampaignEvents extension may be retained indefinitely.
• Sound logo contest: There is a short-term extension applying to data collected as part of contest entries to allow the brand studios team to evaluate entries in preparation for announcing the winner in February 2023. The retained data will be deleted, aggregated or de-identified within 90 days after the winner is announced.
• 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.

新系???

• 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.
