This website uses Matomo On-Premise to generate statistics about the usage of the site. Matomo is fully open-source so that you can check its code and make sure there are no surprises. We do not share this data with third parties.

This site uses cookies – small text files that are placed on your machine to help the site provide a better user experience. In general, cookies are used to retain user preferences, store information for things like shopping carts, and provide anonymised tracking data to third party applications so as to know how visitors interact with the website.

As a rule, we either use cookies to make your browsing experience better or we don’t deploy them at all. This being said, you may prefer to disable all cookies and all sites you visit: the most effective way to do this is to disable them in your browser preferences. The Help section of your browser or the About Cookies website offer guidance for all modern browsers.

The backend of our website is exclusively accessed by members of our team and therefore password protected. For security reasons we track all activity in the backend (including all attempts to log into the backend).

We rely on Wikimedia OAuth to identify users and link them to their Wikimedia account so that they can request Wikipedia-on-demand subsets. Please refer to the WMF’s privacy policy to see how they might handle this data. Your Wikimedia email address may be retrieved during this process: that email address, and any email address you provide to us on the WP1 site, are used solely for sending you notifications when your ZIM files have been processed. We will never sell your email address, or share it with any third party.

This website may contain videos embedded from platforms like YouTube or Vimeo. Please note that these platforms may be able to track your visit on our website and your usage of these videos. For more details, please refer to the YouTube privacy policy or the Vimeo privacy policy.

If you fill in and submit a form on this website, all data you provide is stored on our servers in Germany, operated by Raidboxes (see below). In addition, this data is transferred by email to our staff. Since email is not a secure channel we strongly recommend that you do not transfer any sensitive information through our forms.

Our online donation form is operated by Donorbox (Rebel Idealist LLC, 1885 Mission Street, San Francisco, CA 94103), while payments are processed by Stripe (Stripe, Inc., 185 Berry Street, Suite 550, San Francisco, CA 94107). For more information, please refer to the Donorbox privacy policy or the Stripe privacy policy respectively.
