This privacy policy explains how MarsGroupApp handles information in Police Lights & Police Siren for Android (package: com.marsgroup.policesiren). The app is an entertainment simulator and does not require you to create an account.
The app stores your selected lights and sounds, in-app volume, playback settings, and effects unlocked by watching a video on your device. The app does not request access to your location, contacts, camera, microphone, or photo library.
Google Play processes the one-time Pro purchase and handles payment information. We do not receive your payment card details. The app receives the product and purchase status and verifies the signed purchase record. It caches the verified record locally for offline Pro access and checks with Google Play to restore or update access. We do not include receipts or purchase tokens in our custom analytics events.
The free version uses Google AdMob, including optional rewarded video. Google and its advertising partners may process IP addresses (which can indicate approximate location), advertising or device identifiers, app and ad interactions, and diagnostics to serve and measure ads, prevent fraud, and improve the service. Google’s User Messaging Platform manages consent where applicable. When available, open Settings and choose Ad privacy choices to review or change your selection. You can also manage your advertising ID in Android settings. The app does not request or show ads while Pro access is active.
Firebase Analytics measures app usage, including screen and feature interactions, effect selection, and purchase or advertising flow events. It may process app instance and device identifiers and technical information. We use these reports to understand and improve the app. Firebase Remote Config uses an installation identifier and app information to deliver settings such as ad availability and frequency. See Firebase privacy information and Google’s Privacy Policy for details about Google’s processing.
If you email us, we receive your address and the information you choose to send. We use it to answer your request and keep it only as needed for support and applicable obligations. Clearing the app’s storage or uninstalling it removes local preferences, video unlocks, and the cached purchase record. It does not cancel the Google Play purchase or delete data already processed by Google. You can restore Pro with the Google account that purchased it.
