/**
 * Activity that displays the app's privacy policy for Health Connect permissions.
 *
 * This activity is launched by Health Connect when the user wants to see why the app
 * needs health data access. It displays a WebView with the privacy policy.
 *
 * The privacy policy URL can be customized by defining a string resource named
 * "health_connect_privacy_policy_url" in your app's res/values/strings.xml:
 *
 * ```xml
 * <resources>
 *     <string name="health_connect_privacy_policy_url">https://yourapp.com/privacy</string>
 * </resources>
 * ```
 *
 * Alternatively, you can place an HTML file at www/privacypolicy.html in your assets.
