What should be included in a privacy policy according to best practices?

A comprehensive privacy policy should include a privacy notice, which serves to inform individuals about how their personal information will be collected, used, and shared. This notice is a fundamental element of transparency and is crucial for compliance with various privacy regulations.

While data flows and emergency contacts can be important components in specific contexts, they are not universally required elements of a privacy policy. Data flows would describe how data moves through an organization, which is more relevant in internal documentation or data mapping rather than the policy itself. Similarly, emergency contacts, while useful for operational procedures, do not pertain directly to the essential components of a standard privacy policy aimed at informing users about their privacy rights and the organization's data practices.

Thus, the inclusion of a privacy notice is the core requirement for a privacy policy according to best practices, highlighting its role as the primary means of communication with individuals regarding their privacy.
