“ We’ll only use information you already share This project will address discrimination that's based on perception—so we’ll use first names and profile photos from hosts and guests to help us understand the perceived race someone might associate with them.

We’ll use it to uncover patterns of discrimination We’ll use this information to help us understand when and where racial discrimination is happening on our platform. Any insights will be used to help develop new features and policies that create a more equitable experience for everyone.

Information won’t be tied to your specific account We know your privacy is important, so we analyze trends in bulk and Airbnb won’t associate perceived race information with your account. We won’t use this information in marketing or advertising, and it will only be used for anti-discrimination work.

We consulted with and solicited input from leading civil rights and privacy organizations to guide us We know how delicate this work is—so we developed this work with support and input from leading civil rights organizations like Color Of Change and Upturn, along with privacy organizations like Center for Democracy & Technology, to make sure our approach is both thoughtful and respectful of your privacy.
