Privacy and security for business messages
Every WhatsApp message is protected by the same Signal encryption protocol that secures messages before they leave your device. When you message a WhatsApp business account, your message is delivered securely to the destination chosen by the business.
WhatsApp considers chats with businesses that use the WhatsApp Business app or manage and store customer messages themselves to be end-to-end encrypted. Once the message is received, it will be subject to the business’s own privacy practices. The business may designate a number of employees, or even other vendors, to process and respond to the message.
Some businesses1 will be able to choose WhatsApp’s parent company, Meta, to securely store messages and respond to customers. While Facebook will not show your messages with businesses in anyone's personal Facebook account nor automatically use your messages to inform the ads that you see, businesses will be able to use chats they receive for their own marketing purposes, which may include advertising on Meta. You can always contact that business to learn more about its privacy practices.
Note: The encryption status of an end-to-end encrypted chat cannot change without the change being visible to the user. For more information about which chats are end-to-end encrypted, please read our white paper.
You’re in control
WhatsApp wants to make sure you know what’s happening with your messages. If you don’t want to receive messages from a person or business, you can always block them directly from the chat or delete them from your contact list. We want to make sure you understand how your messages are being handled and have the options you need to make the right decisions for you.
