Data protection

LEO does not record any personal data about its users unless they choose to register with LEO.

Registration data: your personal details

The personal details that you provide to us when you register with LEO are neither passed on to third parties nor used for the purpose of advertising. The data you provide is also not checked for accuracy. However, if you do not provide a valid email address, you will not be able to register, and, for example, obtain access to the LEO language courses. Please note that deliberately providing incorrect data is a contravention of the general provisions in our Terms of Usage / Privacy Policy

After completing the registration process, you can log in at any time to check and amend – as far as this is possible – your personal details in the settings section of My LEO. General information on your personal details can be found in the Four-step guide to the registration process

Purchasing access to courses

The data required for the payment process is collected by our online payment service partner Wirecard GmbH. LEO itself does not have access to your bank details.

Deleting your data

If you would like to have your account deleted, all that is required is an informal email to dict@leo.org requesting that your details be deleted. Please include your user name (Login) and/or alias (nickname) in your email to make it easier for us to identify your account. Your personal details will be deleted within one week of LEO’s receipt of your email. Please bear in mind that deleting your account will also mean that access to any courses you have purchased as well as vocabulary lists you have created will also no longer be available.

Any forum posts that you have made (and which appear under your anonymised alias) will remain unaffected by the deletion of your account and will still be visible to other users. Your alias will remain intact but there will be no personal account attached to it.

Cookies on LEO

  1. In addition to non-personalised cookies, which are required in order to adapt page contents to your browser setting, LEO stores a personalised cookie on your computer that enables LEO to identify your courses, vocabulary lists etc. and also to make it more convenient for you to navigate in the forum, the trainer and on other web pages. If you have not registered and only use the dictionary, this cookie is not stored on your computer. LEO stores another cookie on your computer for the purpose of calculating our user numbers (identifying the number of unique users, not counting page views or the like).
  2. As a matter of principle we do not pass on any information about our users to social networks. The sole exception is if you yourself explicitly choose to do so (by clicking on the icon to “share on Facebook” or “share on G+” from Google).
  3. We use Google Analytics on a large number of our web pages, and this in turn means that Google stores cookies on our users’ computers and records IP addresses visited. To find out more about this, please consult the Google Privacy Policy .

Cookies from Third Parties

Opting out of behavioural online advertising

By using the following links, you can opt out of cookies used by third parties acting on our behalf:LEO also permits other companies (e.g. media agencies) to use cookies to measure the success of advertising and to analyse online advertising and content in order to optimise the advertising you are shown when using our online services. It is possible to  check your current status and activate or deactivate the collection and storing of your personal details by these companies. This consumer portal also provides further information on the subject of behavioural online advertising.

Please note that if you are using a new computer or a different web browser, or if you have deleted the opt-out cookie from your data storage medium, you will have to go through the opt-out process again.

All rights arising in conjunction with the software developed for the purposes of this online service, as well as the databases on which it relies, and all other content belong to LEO GmbH unless another author or proprietor is explicitly named. Any exploitation of the software, the data or any other content except in the form in which it is offered and provided at leo.org is prohibited. In particular, the automatic retrieval of any kind of content via script or in any other manner is forbidden.

Development of toolbars/plug-ins/applets and the like

The development of toolbars/plug-ins/applets and the like (collectively referred to hereinafter as "tools") for internet browsers that are designed to provide direct access to the contents of LEO is permitted only with the prior consent of LEO. Only tools that have been developed with the approval of LEO may be incorporated into internet browsers to provide access to LEO's services.

Tools can only be approved if they carry LEO's name and present the resulting page in exactly the same form as the page for entering a search word that appears on our website dict.leo.org. Approval cannot be granted if advertising displayed on LEO is circumvented by "optimised solutions" that obscure/remove the advertising content.

Links to LEO services are permitted. However, we expect these links to lead directly to LEO's dictionaries, and the page presenting the link must not contain any illegal or pornographic content. The link to be used is: https://dict.leo.org/

Integrating of a search box in other web sites

LEO consents to the integration of a search box for queries to LEO dictionaries in another web site, on condition that:

  • LEO is named in the search box and it is clearly recognisable that the search box initiates a search in LEO dictionaries,
  • the page presenting the results of a search inquiry is displayed unchanged (possibly in a browser window of its own, but not in a frame of the website providing the link) and, in particular, the advertising shall not be obscured.

Your participation and contributions

New entries for the dictionary

LEO welcomes suggestions for new entries provided they are well researched and backed up by reputable sources and/or context examples. You are also asked to read the detailed instructions about creating new entries, which you will find by clicking the  Notes for Users.

The New Entry forum is intended for individual suggestions only. If you would like to submit a whole list of words, the procedure to be followed is explained in the next section.

Donating word lists

If you wish to give us a more extensive collection of words, we will naturally be very happy to hear from you. Please write a brief e-mail to the LEO teamIf you wish to give us a more extensive collection of words, we will naturally be very happy to hear from you. Please write a brief email to the LEO team so that we can coordinate the procedure. We can only integrate word lists for which you hold the copyright. By submitting the word list, you declare your agreement to transfer your collection of vocabulary items to LEO and permit LEO to make use of the data worldwide as required either directly or through third parties (online and offline). In particular, you agree that LEO may replicate and distribute it in all possible forms (in print, on data carriers or in other media) and may make it available for public access by third parties.

Reporting mistakes

To correct simple spelling mistakes, typos etc., please make use of the Report a mistake form.

If you have doubts about the quality or accuracy of entries in the dictionary and would like to read the opinions of other users, check whether there has already been a discussion on this topic in the forum and, if not, launch a new discussion in the  ‘Wrong entry?’ forum. (Please also read the Forums section below.)


Content and use of the forums

The forums (links: German-English, German-French, German-Spanish, German-Italian, German-Chinese, German-Russian, German-Portuguese, German-Polish) are intended to give you the opportunity to ask questions, provide information, make comments and to publish your views on other matters related to the subject of languages and to discuss these with other users. Participation in the forums is subject to the following conditions of use:


Participation in the forums must be preceded by Registration, for which a valid email address must be provided. You may, of course, participate in discussions under a pseudonym (nick/alias). Accordingly, registration requires you to choose a login identity as well as a nick/alias. In principle, you can select the same sequence of characters for your nick as for your login. However, for security reasons you are advised to choose a different sequence of characters for your login to avoid giving third parties an easy way of hacking into your account. You are not permitted to take part in the forums using a number of different nicks and thus to appear in seemingly different identities.

Forum policy

Every user who posts a contribution in our forums agrees irrevocably to the publication of this contribution in the forum concerned. However, the user has no entitlement to force LEO to publish their contributions in a forum.

Contributions must be pertinent, in other words, they must refer to the subject of language. LEO is entitled to erase contributions that are not related to the subject of language. The different sections (sub-forums) are arranged into various topics. Before you use a section for the first time, you are asked to read the notes provided about that section (info link just to the right of the section title). This explains the features of this section and gives instructions about how to start a new thread (discussion). Before initiating a new discussion, you should in any case check whether a corresponding discussion has already been launched on the topic in question by using the forum search. If this is not the case, go to the forum start page (Forum home) and click on the heading of the appropriate section. You can then click the “Start new thread” button to start a new discussion.

Discussions in the forums should be conducted in a courteous and objective manner. Substantive criticism, even if it is quite forceful, is of course permitted. However, defamatory criticism and disparaging personal comments or other remarks that contravene applicable German law are not permitted. Insofar as LEO is aware of forum contributions that contravene German law, LEO reserves the right to inform the public prosecutor accordingly. 

If any content in a forum appears to a user to be illegal or dubious, we ask the user to inform us immediately and send an e-mail to the LEO teamIf any content in a forum appears to a user to be illegal or questionable, we ask the user to inform us immediately by sending an email to the LEO team. Please indicate the reason(s) that the contribution is considered to be illegal or at least questionable, so that we can investigate the matter. Please also send us the URL (address of the contribution in question, shown in the browser's address bar), to enable us to locate the contribution.


Completion of the registration process establishes a contractual relationship between LEO and the registered user. LEO is entitled to ban any user or to terminate this contract immediately if the user violates the above terms of use or behaves in such an unacceptable manner that LEO cannot reasonably continue the contract. In addition, LEO can also remove any individual contributions which are in contravention of the terms of use set out above.

In the event of a termination or the blocking of a contract, the user concerned is not permitted to register again with LEO using the same or another login and/or nick without obtaining prior written consent from LEO

LEO is entitled, but not obliged, to continue to make use of the contributions posted in a forum by the user in question prior to termination of the contract. Contributions that have been erased may not be re-posted.
