We care about your privacy. All WhatsApp messages and calls are secured with end-to-end encryption. This ensures only you and the person you're communicating with can read your messages or listen to your calls, and nobody in between, not even WhatsApp.
In all cases, WhatsApp will deliver your messages to a business end-to-end encrypted. It's important to remember, however, that when you contact a business, several people in that business might see your messages. In addition, some businesses using our WhatsApp Business services may employ another company to manage their communications — for example, to store, read or respond to your messages.
