This is what the official statement has to say,
- helping improve infrastructure and delivery systems;
- understanding how our Services or theirs are used;
- promoting safety, security, and integrity across the Facebook Company Products, e.g., securing systems and fighting spam, threats, abuse, or infringement activities;
- improving their services and your experiences using them, such as making suggestions for you (for example, of friends or group connections, or interesting content), personalizing features and content, helping you complete purchases and transactions, and showing relevant offers and ads across the Facebook Company Products; and
- providing integrations which enable you to connect your WhatsApp experiences with other Facebook Company Products. For example, allowing you to connect your Facebook Pay account to pay for things on WhatsApp or enabling you to chat with your friends on other Facebook Company Products, such as Portal, by connecting your WhatsApp account.
