MarsGroupApp provides Whip Sound - Whip Simulator for Android (package com.whip.sounds.www). This policy describes how the Android app handles information. The app does not require a MarsGroupApp account.
On-device settings and permissions
The app stores your playback preferences, such as shake, vibration and flash settings, and its rating prompt state on your device. It reads motion sensor data locally to detect a shake while you are on the playback screen. If you enable the flashlight, the app may ask for camera permission to control the LED. It does not take photos, record video or send camera or motion data. You can revoke the camera permission in Android settings.
Google Play purchases
Google Play handles payment for the one-time Pro upgrade. MarsGroupApp does not receive your payment card details. The app uses the signed purchase record, including the product, status and purchase token, to verify or restore Pro. It saves the verified record on the device for offline access and checks purchase status with Google Play.
Advertising and privacy choices
When ads are enabled in a build, the free version can use Google AdMob and Google's User Messaging Platform. Google and its advertising partners may process IP addresses (which can indicate approximate location), device or advertising identifiers, app or ad interactions, and diagnostics for ad delivery, measurement, fraud prevention and consent management. Where available, use Privacy Options in the app's Settings or manage your advertising ID in Android settings. Pro disables in-app ads.
Analytics and remote configuration
When Firebase is configured in a build, Firebase Analytics may receive usage events, app or device identifiers and technical information to help us understand and improve the app. Firebase Remote Config may use an installation identifier and app information to deliver settings such as ad timing. Google processes this information for these services. For more information, see Google's Privacy Policy at https://policies.google.com/privacy and Firebase privacy information at https://firebase.google.com/support/privacy.
Retention, deletion and contact
Settings and the cached purchase record remain on your device until you clear the app's storage or uninstall it. This does not cancel a purchase or erase information already handled by Google. If you contact us, we use your email address and the information you send to respond and retain it as needed for support and applicable obligations. You can contact MarsGroupApp at marsgroupapp@gmail.com with privacy questions or to request deletion of information we hold. You can manage information held by Google through your Google account.
