はじめに

データは大切です。データは、私たちが組織として、また、運動として、学びそして成長するための方法の一つです。また、これらのプロジェクトを使って創造し、学び、そしてシェアする人達のために、これらのプロジェクトをより良いものにするための、方法の一つでもあります。

それと同時に私たちは、あなたの私的なデータを、「可能な限り短い期間だけ持っておく」ことにコミットしています。ここでいう「可能な限り短い」の意味は、「各ウィキメディア・サイト(Wikimedia Sites)のメンテナンス、理解、改善という目的に合致し、また、該当する米国法の下での私たちの法的義務にも合致する」、ということです。(上記の引用は、ウィキメディア財団のプライバシー方針からのものです)

This document helps explain how we fulfill this commitment, by describing our guidelines for data retention, system design, and ongoing auditing and maintenance. These guidelines are meant to be a living document — they will be updated over time to reflect current retention practices.

これらのガイドラインはどんなデータに適用されるのか

これらのガイドラインはウィキメディアのサイトで収集され、プライバシーポリシーで保護される全ての公開でないデータに適用されます。

非公開のデータを保持する期間の長さはどれくらいか

Unless otherwise indicated, we retain the following types of data for no more than the following periods of time:

How long do we retain public data?

Wikimedia hosts Wikipedia and the associated projects as part of our mission to collect, document, and freely distribute the sum of human knowledge to the world. 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 oversight policy. 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.

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 renamed, or goes through the community courtesy vanishing process.

For more information, see our Privacy Policy.

定義

これらのガイドラインの目的のために:

  • 「個人情報」 はあなたが提供する情報または当財団が収集する情報のうち、それを使ってあなた個人を特定することができる情報のことです。当財団は下記の種類の情報すべてを収集しているとは限らないことを念のため記しておきますが、当財団が「個人情報」であると見なす条件とは、下記のものが他の場で非公開になっていて、あなたを特定できる目的で使用できる場合が、「個人情報」だと考えます。
  • 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 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.

An example of how data can be aggregated includes:

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.

これらのガイドラインの例外

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

  • Data may be retained in system backups for longer periods of time, not to exceed 5 years.
  • 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.
  • 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.

新しいシステムの設計

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.

Ongoing handling of new information

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.
