The director of the Federal Trade Commission’s Bureau of Consumer Protection notified Facebook and WhatsApp about their obligations to protect the privacy of their users in light of Facebook’s proposed acquisition of WhatsApp.

In a letter to the two companies, Bureau Director Jessica Rich noted that WhatsApp has made clear privacy promises to consumers, and that both companies have told consumers that after any acquisition, WhatsApp will continue its current privacy practices.

“We want to make clear that, regardless of the acquisition, WhatsApp must continue to honor these promises to consumers. Further, if the acquisition is completed and WhatsApp fails to honor these promises, both companies could be in violation of Section 5 of the Federal Trade Commission (FTC) Act and, potentially, the FTC’s order against Facebook,” the letter states.F.T.C.
