Accordingly, when you make a contribution to any Wikimedia Site, including on user or discussion pages, you are creating a permanent, public record of every piece of content added, removed, or altered by you. The page history will show when your contribution or deletion was made, as well as your username (if you are signed in) or your IP address (if you are not signed in). We may use your public contributions, either aggregated with the public contributions of others or individually, to create new features or data-related products for you, or to learn more about how the Wikimedia Sites are used. If you mistakenly included your personal information in a contribution to a Wikimedia Site and you would like to have it removed, please consult the community's <a href="https://meta.wikimedia.org/wiki/Special:MyLanguage/Oversight_policy" class="extiw" title="m:Special:MyLanguage/Oversight policy">oversight policy</a>. Keep in mind that the transparency and integrity of our sites' revision histories is essential to our mission, and the Foundation supports our community's right to reject oversight requests in order to protect the projects. </p><p>If you choose to register for an account with the Wikimedia projects, you will be asked to select a username. Usernames are retained until the user requests that the account be <a href="https://meta.wikimedia.org/wiki/Special:MyLanguage/Changing_username" class="extiw" title="m:Special:MyLanguage/Changing username">renamed</a>, or goes through the community <a href="https://meta.wikimedia.org/wiki/Special:MyLanguage/Courtesy_vanishing" class="extiw" title="m:Special:MyLanguage/Courtesy vanishing">courtesy vanishing</a> process. </p><p>For more information, see our <a href="/wiki/Special:MyLanguage/Policy:Privacy_policy#use" title="Special:MyLanguage/Policy:Privacy policy">Privacy Policy</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Definitions">Definitions</h2></div> <p>For the purposes of these guidelines: </p> <ul><li><b>"Personal information"</b> means information you provide us or information we collect from you that identifies or could be used to personally identify you.

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.</li> <li>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 <a href="https://www.wikidata.org/wiki/Q84263196" class="extiw" title="d:Q84263196">COVID-19</a>, <a href="https://www.wikidata.org/wiki/Q82069695" class="extiw" title="d:Q82069695">SARS-CoV-2</a> and <a href="https://www.wikidata.org/wiki/Q81068910" class="extiw" title="d:Q81068910">2019-2020 COVID-19 pandemic</a> 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 <a rel="nofollow" class="external text" href="https://github.com/geohci/covid-19-sessions">the project page on GitHub</a>.</li> <li>Editing research: There is a short-term extension applying to data collected as part of <a href="https://www.mediawiki.org/wiki/Talk_pages_project/replying" class="extiw" title="mw:Talk pages project/replying">experimental features to improve replying on talk pages</a>. 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.</li> <li>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.

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.</li> <li>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.</li> <li>Webrequest datasets: There is a short, one-time extension for data from the wmf.webrequest and wmf.pageview_actor datasets. This data needs to be retained longer than usual while we correct an error in the way unique devices are calculated from the dataset. Accurate unique device statistics are necessary for engineering purposes and legal reporting requirements.
