Facebook Open Source – Privacy Policy

Effective Date: March 15, 2020

This policy describes our practices for handling your information on this website (the “Services”).

Collection of Information

When you interact with us through our Services, we may collect or receive the following types of information:

Information you provide directly to us. For certain activities, we may collect the
following types of information:
• Contact information, such as name and email address; and
• Information you provide us when you send us correspondence, comment on posts, subscribe to a service, or otherwise participate on the Services.

Information we collect automatically. We may also collect certain information
automatically when you use our Services, such as your Internet protocol (IP) address, mobile device identifier, browser type, operating system, Internet service provider, pages that you visit before and after using the Services, the date and time of your visit, information about the links you click and pages you view within the Services, and other standard server log information.

Integrations with Social Networking and Other Services. Our Services allow you to enable or log in via various online services, such as Facebook, Twitter or Youtube (collectively, “platforms”). Our Services may enable you to access these platforms directly or indirectly through our Services. By including these platforms, we aim to make your online experiences richer and more personalized. When you add a platform account to our Services or log into our Services using your platform account, we may collect relevant information necessary to enable our Services to access that platform and your data that platform holds. We may also share your information with that platform to facilitate or enhance the delivery of that platform or our Services.

As part of an integration with a platform, that platform may provide us with access to certain information that you have provided to the platform, and we will use, store, and disclose such information in accordance with this Privacy Policy. However, please remember that the manner in which platforms use, store, and disclose your information is governed by the policies that apply to those platforms.

Information we obtain from other sources. We may receive information about you from other sources, including through third-party services and organizations, which we may combine with other information we receive about you.

How We Use Information

We may use the information you provide us to:
Meet our legitimate interests, including to fulfill your requests for resources,
services, and information; analyze the use of the Services and user data to understand, improve and operate the Services; and customize the content you see when you use the Services;
Meet our legal obligations, including to prevent potentially prohibited or illegal activities and otherwise in accordance with our Terms of Use and comply with legal requirements; and
For any other purposes disclosed to you at the time we collect your information or pursuant to your consent.

How We Share Information

There are certain circumstances in which we may share your information with certain third parties without further notice to you, as set forth below:
Authorized third-party vendors and service providers. We share your
information with third-party vendors and service providers that help us with specialized services, including email deployment, business analytics, marketing, and data processing. These services providers are limited from using your information for any purpose other than to perform services for us.
Affiliates. We may share your information with our affiliates, which are companies that control, are controlled by, or are under common control with us.
Legal purposes. We may disclose information to respond to subpoenas, court orders, legal process, law enforcement requests, legal claims or government inquiries, detect fraud, and to protect and defend the rights, interests, safety, and security of Facebook, our affiliates, owner, users, or the public.
Business transfers. We may share your information in connection with a substantial corporate transaction, such as the sale of a website, a merger, consolidation, asset sale, or in the unlikely event of bankruptcy.
With your consent. We may share information for any other purposes disclosed to you at the time we collect the information or pursuant to your consent. If you choose to engage in public activities on the website, you should be aware that any information you share there can be read, collected, or used by other users of these areas. You should use caution in disclosing personal information while participating in these areas. We are not responsible for the information you choose to submit in these public areas.

How We Protect Information

We take measures to help protect information from loss, theft, misuse and unauthorized access, disclosure, alteration, and destruction. However, no data storage system or transmission of data over the Internet or any other public network can be guaranteed to be 100 percent secure. Please note that information collected by third parties may not have the same security protections as information you submit to us, and we are not responsible for protecting the security of such information.

Your California Privacy Rights

We do not share personal information with third parties for their own direct marketing purposes.

Do-Not-Track Signals and Similar Mechanisms. Some web browsers transmit “do-nottrack” signals to websites. Because of differences in how web browsers incorporate and activate this feature, it is not always clear whether users intend for these signals to be transmitted, or whether they even are aware of them. We currently do not take action in response to these signals.

Children’s Information

Facebook does not knowingly collect or store information from children under the age of 13, unless permitted by law. We will delete any information we may have inadvertently received from a child under 13 upon notice. If you have reason to believe that a child under the age of 13 has provided personal information to Facebook through our Services please contact us and we will endeavor to delete that information from our databases.


We may use cookies, pixel tags, and similar technologies to automatically collect this information. Cookies are small bits of information that are stored by your computer’s web browser. Pixel tags are very small images or small pieces of data embedded in images, also known as “web beacons” or “clear GIFs,” that can recognize cookies, the time and date a page is viewed, a description of the page where the pixel tag is placed, and similar information from your computer or device. By using the Services, you consent to our use of cookies and similar
technologies. You may be able to refuse or disable cookies by adjusting your web browser settings. Because each web browser is different, please consult the instructions provided by your web browser (typically in the “help” section). For EU visitors, we provide a tool allows you to manage cookies you would like to receive and their relevant usage.

Changes to this Policy

We may update or modify this Privacy Policy at any time without prior notice. When we update the Privacy Policy, we will revise the “Effective Date” date above and post the new Privacy Policy. We recommend that you review the Privacy Policy each time you visit the Services to stay informed of our privacy practices. Any changes will be effective when we post the revised policy. Your continued use of our Services after any changes or revisions to this Privacy Policy shall
indicate your agreement with the terms of such revised Privacy Policy.
