1 Wikimedia projects belong to everyone

You made it. It is yours to use. For free. That means you can use it, adapt it, or share what you find on Wikimedia sites. Just do not write your own bio, or copy/paste it into your homework.

2 We respect your data and privacy

We do not sell your email address or any of your personal information to third parties. More information about our privacy practices are available at the Wikimedia Foundation privacy policy, donor privacy policy, and data retention guidelines.

3 People like you keep Wikipedia accurate

Readers verify the facts. Articles are collaboratively created and edited by a community of volunteers using reliable sources, so no single person or company owns a Wikipedia article. The Wikimedia Foundation does not write or edit, but you and everyone you know can help.

4 Not all wikis are Wikimedia

The word “wiki” refers to a website built using collaborative editing software. Projects with no past or existing affiliation with Wikipedia or the Wikimedia Foundation, such as Wikileaks and wikiHow, also use the term. Although these sites also use "wiki" in their name, they have nothing to do with Wikimedia.

Projects — Projets

Collaborative projects are the core of the Wikimedia movement.

Our volunteers build tools, share photos, write articles, and are working to connect all the knowledge that exists.

As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.
