The primary purpose of a privacy policy is to inform users about how an organization handles their personal data. It serves as a legal disclosure that explains what information is collected, how it is used, stored, and protected, and whether it is shared with third parties.
Key functions of a privacy policy include:
Transparency and Trust: It builds trust by being open about data practices, allowing users to make informed decisions about using a service.
Legal Compliance: It ensures the organization meets legal requirements set by data protection laws such as the GDPR (Europe), CCPA (California), and others, which mandate that users be informed about data collection.
User Rights: It outlines the rights users have regarding their data, such as the right to access, correct, or delete their information.
Risk Management: It helps limit the organization's liability by clearly stating its practices and terms, which can be crucial in the event of legal disputes or data breaches.
Third-Party Requirements: Many third-party services, such as app stores (Google Play, Apple App Store) and advertising networks (Google AdMob), require a privacy policy to operate on their platforms.
In the context of your app, the privacy policy specifically informs users that no personal data is collected directly by the app, but that third-party services like AdMob may collect data such as device identifiers and location for advertising and analytics purposes. It also clarifies that calculations occur locally on the user's device.
