Our Terms of Use

Imagine a world in which all of human knowledge is freely accessible to everyone. That is our goal. - Our vision

Welcome to Wikimedia! The Wikimedia Foundation, Inc. ("We" or "us") is a non-commercial charitable organization whose mission is to empower and motivate people around the world to compile and develop content that is under a free license or in the public domain, and to distribute it free of charge, effectively and worldwide.

In order to support our living community, we provide the basic infrastructure and the organizational framework for the development of the multilingual Wiki projects and their versions (as described in more detail here) as well as for other projects that serve this goal. It is our aim to make the information and educational content available in our projects available on the Internet free of charge on a permanent basis.

We welcome you (“you” or the “user”) as a reader, editor, author or contributor to the Wikimedia Projects and encourage you to join the Wikimedia community. Before doing so, however, we would ask you to read and agree to the following terms of use (“Terms of Use”).


These terms of use inform you about the public services of the Wikimedia Foundation, our relationship with you as a user and about the rights and obligations to which we are based. We want you to know that we provide a tremendous amount of educational and informational content, all of which has been contributed by users like you. We ourselves generally do not participate in the creation, monitoring or deletion of content (with the rare exception of guidelines such as these terms of use or changes that are necessary to ensure compliance with legal provisions of the DMCA notice procedure). This means that content control is in your hands and those of the other users who create and manage content. We only provide this content.

The community - the network of users who use the various sites and projects and continuously work on building them - is the primary means by which our goals are achieved. The community contributes to our pages and helps us to manage them. It performs the important task of creating and enforcing rules for the respective project versions (for example the different language versions of the Wikipedia project or the multilingual Wikimedia Commons).

We invite you to contribute as a contributor, editor or author. You should, however, observe the rules that apply to each of the independent project versions. Our largest project is Wikipedia, but we also have other projects, each with their own goals and working methods. In each of these project versions, a group of contributors, editors and authors work together to create and manage the content of the respective project version. We invite you to join these groups and work with them to improve the projects. Since we are committed to making content freely available to the public, it is fundamentally necessary that all content that you contribute is under a free license or is in the public domain.

Please note that you are responsible for all your contributions, adaptations and further use activities under the law of the United States of America and other applicable legal systems (including, if applicable, those of the country in which you live or view or edit the content). For this reason, it is important that you use caution when posting content. In light of this responsibility, there are a few rules about what not to post, most of them either for your own protection or that of other users. Please remember that the content we provide is for general information only; therefore, if you need expert advice on specific issues (such as medical, legal or financial matters), you should seek the help of recognized or qualified professionals. Since these terms of use also contain other important information and disclaimers, we ask you to read them completely.

To clarify, it should be noted that other organizations such as local Wikimedia associations or associations, which sometimes pursue the same goals, are nevertheless legally independent and different from the Wikimedia Foundation and that they are not responsible for the processes or content of the website.

1. Our services

The Wikimedia Foundation is committed to promoting the expansion, development and distribution of free content in a variety of languages ​​and to making the entire content of these Wiki-based projects available to the public free of charge. Our role is to provide some of the largest collaborative reference works in the world; the individual projects can be found here. However, we only act as a hosting service. In this role, we maintain the infrastructure and provide the organizational framework that enables our users to build up the Wikimedia projects by contributing new content and editing existing ones. Because of our unique role, there are a few things you should be aware of about our relationship with you, the projects, and other users.

  1. We do not play an editorial role: Because the Wikimedia projects are worked on jointly, all content made available is brought in by users such as yourself; we have no editorial role in this. This means that we generally do not monitor or edit project content and do not assume any responsibility for it. Accordingly, we do not adopt any opinions expressed about our services as our own. We do not guarantee or promise that any user-submitted content will be truthful, correct or reliable. Rather, we simply provide access to the content that other users have contributed and edited.
  2. You are responsible for your actions: You are legally responsible for your edits and contributions to Wikimedia projects, which is why it is advisable for your own protection to exercise caution and avoid contributions that could result in criminal or civil consequences in one of the applicable legal systems. The applicable legal systems include at least the law of the United States of America. Even if we may not agree with such measures, we warn the processor and contributor that authorities may try to apply the legal norms of other countries to your actions, for example the laws in your place of residence or the place where you view content or edit, apply. In principle, the Wikimedia Foundation cannot provide protection, guarantees, immunity or compensation.

5. Password security

It is your responsibility to protect your password and you should never pass it on to third parties.

6. Brands

Even if you are granted considerable freedom with regard to the continued use of content on the project websites, it is important that we, the Wikimedia Foundation, protect our trademark rights in order to protect our users from imitators who pursue fraudulent intentions. For this reason we would like to ask you to respect our trademark rights. All Wikimedia Foundation trademarks are owned by the Wikimedia Foundation and any use of our trademarks, brands, service marks, logos, or domain names must be in accordance with these Terms of Use and our Trademark Policy.

7. Licensing of Content

In order to promote the expansion of free knowledge and free culture as common goods, all users who contribute to the projects must grant the general public extensive powers to disseminate and re-use their contributions, subject to the fact that in such use the naming rights are respected and with regard to the re-use and redistribution of derivative works will again be given the same freedoms. In order to adhere to our goal of making free information available to the broadest possible audience, we require that all transmitted content be licensed, if necessary, so that it can be freely used by anyone who wants to access it.

You agree to the following license terms:

  1. Texts to which you hold the copyright ["copyrights"]: If you submit any text that you have copyrights to, you agree to license it under the. (Additional users can use one of the licenses or both.)

    The only exception is if the project version or the function requires a different license. If so, you agree to make any text you contribute subject to this particular license. At the time of publication of these terms of use, for example, the English version of Wikinews requires that all text content is published under the license Creative Commons Attribution 2.5 US (unported) (CC-BY 2.5), whereby there is no double licensing together with the GFDL needs.

    Please note that these licenses allow the commercial use of your contributions, provided that the conditions are observed for the respective use.
  2. Attribution: Attribution is an important part of these licenses. We see this as recognition of the work of authors like yourself. When you contribute, you agree to be named in one of the following ways:
    1. By hyperlinking the article (if possible) or by specifying the URL of the article to which you have contributed (since every article has a version history listing all authors and editors);
    2. By hyperlink (if possible) or URL to another stable online copy that is freely accessible, complies with the license and guarantees the attribution of the authors in a way that is equivalent to that on the project websites; or
    3. Through a list of all authors (please note, however, that each list of authors can be filtered in order to clean up very small or irrelevant contributions).
  3. Import of texts: You can import texts that you have found elsewhere or that you have co-authored with others, in which case you guarantee that the texts are available under conditions compatible with the CC-BY-SA-3.0 license are (or, as stated above, with a different license, if this is exceptionally required by the project version or the function) ("CC-BY-SA"). Content that is only available under the GFDL is not permitted.

  4. If you import texts under a CC-BY-SA license that require attribution, you must appropriately name the author (s). In cases in which the name is usually given using the version history (such as the internal transfer of content at Wikimedia), it is sufficient to comply with the obligation to give names in the processing summary, which is saved in the version history. The attribution requirements are sometimes too restrictive (regardless of the respective license) under certain conditions and there may be cases in which the Wikimedia community comes to the conclusion that imported texts cannot be used for this reason.
  5. Non-textual media: Non-textual media are available in the projects under a large number of different licenses, which are conducive to the general goal of unrestricted further usability and redistribution. When you contribute non-textual media, you agree to act in accordance with the terms and conditions of such licenses as set out in our Licensing Policy and also to meet the requirements of the specific project version or role you are contributing to. See the Wikimedia Commons Licensing Policy for more information on contributing non-textual media to Wikimedia Commons.
  6. No revocation of the license: Except to the extent that your selected license permits, you agree that you will not be granted any license under these Terms of Use for text or non-textual content that you have contributed to Wikimedia projects or functions unilaterally revoke them or work towards their repeal, not even if you stop using our services.
  7. Public domain content: Public domain content is welcome! However, it is important that you check that the content is in the public domain, both under the laws of the United States of America and those legal systems of other states that the specific project version requires to be taken into account. When you contribute content that is in the public domain, you guarantee that this material is actually in the public domain and you agree to mark it accordingly.
  8. Further use: We invite you to continue using the content we have made available, although there are exceptions for such content that was contributed under the "fair use" doctrine or a similar copyright exception. Any act of further use must comply with the provisions of the underlying license (s).

    If you continue to use or redistribute a text page developed by the Wikimedia community, you agree to name the authors in one of the following ways:
    1. By a hyperlink to the page (s) (if possible) or by specifying the URL of the page (s) that you continue to use (since every page has a version history in which all authors and editors are listed);
    2. Through a hyperlink (if possible) or URL to another stable online copy that is freely accessible, complies with the license and guarantees the attribution of the authors in a way that is equivalent to that on the project websites; or
    3. Through a list of all authors (please note, however, that each list of authors can be filtered in order to clean up very small or irrelevant contributions).

    If the text content was imported from another source, it is possible that the content is licensed under a compatible CC-BY-SA license, but not under the GFDL (as described above under "Importing Texts"). In this case, you agree to comply with the license terms of the compatible CC-BY-SA license and acknowledge that you do not have the option to further license the content under the GFDL. To determine which license the content that you want to reuse or redistribute is subject to, you should check the page footer, version history, and talk page for this information.

    Furthermore, we ask you to note that text content that comes from an external source and has been imported into a project may be under a license that places additional requirements on attribution. Users agree to clearly indicate such additional attribution requirements. Depending on the project, such information can be provided, for example, by means of a banner or other display method that indicates that some or all of the content was originally published in a different location. Where there are such visible signs, further users should keep them.

    With respect to all non-textual media, you agree to abide by a license under which the work was made available (this can be viewed by clicking on the work and consulting the licensing section on the resulting description page, or by clicking on an appropriate one Source side of the work). If you continue to use the content made available by us, you agree to comply with the relevant attribution requirements, insofar as these are provided for in the underlying license or licenses.
  9. Edits or additions to re-used material: If you make changes to or add to text that you have obtained from a project website, you agree to the edited or added content under CC-BY-SA 3.0 or a later version (or, as stated above, under another license, if this is exceptionally required by the specific project version or function).

    If you make changes to or additions to any non-textual content obtained from a project website, you agree to license the edited or added content in accordance with a license under which the work was made available.

    With regard to both text and non-textual content, you agree to clearly state that the original work has been changed. If you continue to use text content in a wiki, it is sufficient to state in the version history of the page that you have made a change to the imported text. With respect to any copy or modified version that you distribute, you agree to include a license notice stating the license to which the work is subject and which also contains either a hyperlink or URL pointing to the license text or a Copy of the license itself.

8. Compliance with the DMCA

The Wikimedia Foundation wants to ensure that the content we hold can continue to be used by other users without them having to fear liability consequences or an infringement of third-party property rights. In fairness to our users and other authors and copyright holders, our process provides for responding to notifications of suspected legal violations that meet the formal requirements of the Digital Millennium Copyright Act (DMCA). According to the DMCA, we will, under certain circumstances, terminate users and account holders from our system and network who have repeatedly committed legal violations.

However, we also acknowledge that not every takedown notice is valid or made in good faith. In such cases, we strongly encourage our users to submit a counter-notification if they reasonably believe that a DMCA take-down claim is invalid or unjustified. Please visit the Chilling Effects website for more information on what to do if you believe a DMCA notice was wrong.

If you are the rights holder of content that is used unauthorized and without your permission on one of the project websites, you can request that this content be removed with reference to the DMCA. In order to send us a corresponding request, we ask you to send us an email at to inform about it or to contact our Designated Agent by post. The address can be found on this page.

Alternatively, you can also contact the user community with a request; as a result, copyright problems can often be eliminated faster and more effectively than is the case under the DMCA process. To do this, you can leave a note in which you draw attention to your copyright concerns. An incomplete and non-binding list of the relevant procedures in the individual project versions can be found here. You can also contact the community using the email address before filing a DMCA claim.

9. Third Party Internet Offers and Resources

You are solely responsible for your use of third party websites and resources. Even if the projects contain links to internet offers or resources of third parties, we do not approve of them and are neither responsible nor liable for their availability, accuracy or for related content, products or services (including, without claiming to be exhaustive, any existing viruses or others) undesired functions) nor are we in any way obliged to monitor such third-party content.

10. Management of Internet offers

The community has the most important role in developing and enforcing rules for the various project versions. At the Wikimedia Foundation, we rarely intervene in community decisions about rules and their enforcement. In exceptional cases, it may be necessary or a request from the community that we deal with a problematic user who is causing significant project disruptions or who is noticeable through dangerous behavior. In such cases we reserve the right, but are not obliged to:

  • Investigate how you use the Services (a) to determine whether there has been a breach of these Terms of Use, Project Version Policies, or any other applicable law or policy, or (b) any applicable law, legal process, or reasonable government request to comply;
  • to identify fraudulent, security-relevant or technical problems, to ward them off, to counter them in other ways or to answer corresponding user inquiries;
  • deny, make unavailable or restrict access to the contributions of a user who violates these Terms of Use;
  • revoke a user 's permission to edit or contribute, or suspend a user' s account or access right for any action that violates these Terms of Use, including repeated copyright infringement;
  • Take legal action against users who violate these Terms of Use (including reporting to law enforcement agencies); and
  • manage the project websites in a way that is appropriate to facilitate their proper functioning and to protect the rights, property and safety of ourselves and our users, licensees, partners and the public.

In the exceptional event that someone's user account or access rights have been blocked due to this provision, this person is prohibited from creating, using or attempting to create another user account on the same project without our express permission in the interests of our users and the projects To provide access to the same project. Without restricting the decision-making authority of the community, the Wikimedia Foundation will not withdraw the authorization to edit or contribute to any user, or block a user account or access right because the user expresses criticism in good faith that does not result in actions that would otherwise be Violate these Terms of Use or any community guidelines.

The Wikimedia community and its members may also take action as provided by the community or foundation policies applicable to the specific version of the project, including, but not limited to, warning, investigating, banning, or banning users from violating these rules violate. You agree to act upon the final decisions of dispute resolution bodies established by the community for specific project versions (such as arbitration tribunals); These decisions can consist of sanctions, the scope of which depends on the rules applicable in the respective project version.

Particularly problematic users, whose user accounts or access rights have been blocked on different project versions, can be excluded from all project versions in accordance with the guideline for global prohibitions.Unlike resolutions of the Board of Trustees or provisions of these Terms of Use, guidelines drawn up by the community may refer to a single project version or to multiple project versions (as is the case with the Global Prohibition Directive) by the respective relevant community can be changed according to their own stipulations.

The blocking of a user account or access right or the exclusion of a user under this provision shall take place in accordance with Section 12 of these Terms of Use.

11. Guidelines and project rules

The Board of Trustees of the Wikimedia Foundation issues official guidelines from time to time. Some of these guidelines may be mandatory for specific projects or project versions. If this is the case, you agree to follow these rules as far as they are individually applicable.

12. Termination
