# Introduction to privacy frameworks

> Learn how the Unity Ads SDK provides APIs to help you communicate user consent, opt-out choices, and age designations programmatically.

Privacy regulations define how user data can be collected, used, and shared in digital advertising. For publishers integrating Unity Ads, understanding these requirements ensures your app handles user data responsibly and in compliance with applicable laws and platform policies.

The Unity Ads SDK provides APIs to help you communicate user consent, opt-out choices, and age designations programmatically. By configuring privacy signals correctly, your app can automatically adjust ad behavior.  For example, serving contextual ads to underage users or disabling personalized ads when consent is not granted, while maintaining compliance across supported regions.
