Bienvenue !

Tel que mentionné dans notre politique de respect de la vie privée, Wikimedia croit fermement dans les valeurs de la transparence et de la vie privée. À cette fin, nous avons créé cette « Déclaration sur l'utilisation des témoins » afin d'offrir un guide de référence clair sur l'utilisation que nous faisons des témoins sur les sites Web de Wikimedia. Cette « Déclaration » explique comment nous utilisons les témoins ainsi que d'autres technologies qui peuvent conserver des données localement, comment sont utilisés les témoins des tierces-parties par les sites Web de Wikimedia, ainsi que vos options pour gérer l'utilisation des témoins. Pour plus d'informations sur nos pratiques de protection de la vie privée, SVP consultez notre politique de respect de la vie privée.

The Wikimedia Foundation, the non-profit organization that hosts the Wikimedia Sites, actively collects some types of information with a variety of commonly-used technologies. These generally include tracking pixels, JavaScript, and a variety of "locally stored data" technologies, such as cookies and local storage.

1. Qu'est-ce qu'un témoin (cookie) ?

A “cookie” is a tiny data file that we transfer onto your computer, mobile phone, or any other device that you use to access the Wikimedia Sites, generally used for authentication and tracking. Every cookie expires after a certain period of time, but that period varies depending on what the cookie is used for and how your browser is configured.

Un « témoin de session » est un témoin qui expire lorsque vous fermez votre navigateur internet ou votre application. Un témoin « persistent » sera plutôt enregistré par votre appareil et restera présent même après la fermeture de votre navigateur ou application. Un « témoin persistant » restera présent pendant la durée choisie par nous, à moins que vous l'effaciez manuellement avant ou que vous avez configuré votre navigateur pour les gérer comme des témoins de session. En apprendre plus sur Wikipédia.

Vous pouvez effacer ou désactiver ces témoins via les options de configuration de votre navigateur. Pour plus informations sur vos options pour gérer les témoins, veuillez consulter la section 5 de cette « Déclaration sur l'usage des témoins ».

For more information on this and other key terms that may be relevant, please read through our Privacy Policy Glossary.

2. Comment nous utilisons les témoins (cookies) ?

We use the information we receive from cookies and other locally stored data to make your experience with the Wikimedia Sites safer and better, to gain a greater understanding of user preferences and interactions with the Wikimedia Sites, and to generally improve our services.

Cookies and other locally stored data, JavaScript, and tracking pixels help us do things like:

• Provide you with a personalized experience, such as using cookies to know your language preference, to remember the user preferences you set so we can provide you with the customized look and feel that you want, and to tell you about interesting Wikimedia issues and events in your area.
• Deliver more relevant content to you faster. For example, we may use local storage to store your most recently read articles directly on your device, so they can be retrieved quickly. Also, we may use cookies to learn about the topics searched so that we can optimize the search results we deliver to you.
• Understand how you use the Wikimedia Sites, so that we know what works and what is useful. For example, we might use cookies to learn about the list of articles you are following on your watchlist so that we can recommend similar articles that you may be interested in.
• Understand how you use the Wikimedia Sites across different devices, so that we can make our varied Wikimedia Sites more efficient and effective for you.
• Make the Wikimedia Sites more convenient to use, such as by using cookies to maintain your session when you log in or to remember your username in the login field.

3. Quels sont les types de témoins (cookies) que Wikimedia utilise?

The cookies and other locally stored data technologies used by the Wikimedia Sites generally fall into the following categories:

• Functionality: These cookies help the Wikimedia Sites work, including essential features like logging in.
• Preferences: These cookies store your preferences, so that they can be remembered the next time you use the Wikimedia Sites.
• Performance and Analysis: These cookies collect information about how you use the Wikimedia Sites, so that we can better understand how the Wikimedia Sites work and improve them for you and other users.
• Third-Party: These cookies allow us to render services provided by third parties, such as “like” and “share” buttons. When a third party provides these kinds of services, they may require the use of a cookie in order to provide their services. (These kind of cookies would only be used with your permission.)

For more specific examples, we have provided the table below. But before you start reading, here is some background on Cookie Prefixes ("{$wgCookiePrefix}") you’ll find in the table.

Many of the Wikimedia Sites are technically separate sites – for example, French Wikipedia is different from English Wikipedia, and both are separate from French Wikibooks. As a result, we may set different cookies for different Wikimedia Sites. To help you (and your computer!) tell the Wikimedia Sites apart, each Wikimedia Site may set cookies that reflect their name. For example, enwikiUserName is a cookie that sets your username in “enwiki” - i.e., in English Wikipedia. frwikinewsUserName is a cookie that sets your username in “frwikinews” - i.e., in French Wikinews. We could list 800+ versions of UserName (one for each language and project), but instead this table will just have one entry for “UserName” - {$wgCookiePrefix}UserName. Wherever you see {$wgCookiePrefix}, that means you'll get one copy of the cookie for each of the Wikimedia Sites that you visit, and the name will be the “cookie prefix” (like enwiki, frwikinews, etc.) plus the rest of the name.

And now on to the table!

4. How do third parties use cookies on Wikimedia Sites?

Third-party cookies allow us to render services provided by third parties, such as “like” and “share” buttons. When a third party provides these kinds of services, they may require the use of a cookie in order to provide their services.

We will never use third-party cookies, unless we get your permission to do so. If you ever come across a third-party data collection tool that has not been authorized by you (such as one that may have been mistakenly placed by another user or administrator), please report it to us at privacywikimedia.org.

5. What are my cookie options?

While this is not a comprehensive list, here are some of the things that you can do to limit use of cookies and other locally stored data on your device. You can:

• remove or disable specific locally stored data on your browser’s settings;
• use a browser that can block third-party cookies; or
• install a plug-in to block locally stored data, if one is available.

We believe this data collection helps improve your user experience, but you may remove or disable some or all locally stored data through your browser settings, depending on your browser. You can learn more about some options you have in our FAQ. While cookies and other locally stored data may not be necessary to use our sites, some features may not function properly if you disable locally stored data.

6. Where can I find more information?
