GNIS ("Reverse Karaoke") is a mobile game developed by Masami Kawamoto. We respect your privacy and aim to collect as little information as possible while providing the functionality of the app.
GNIS does not require users to create an account and does not collect personal information such as names, email addresses, phone numbers, location data, contacts, photos, or recordings. To support in-app purchases and purchase restoration, GNIS uses RevenueCat, a third-party service that receives: • A randomly generated app user identifier used to manage purchase entitlements. • Information related to purchases made within the app. This information is used solely to unlock purchased features, restore purchases, and ensure the app functions correctly.
GNIS requests access to your device's microphone solely to enable reverse karaoke gameplay. Audio is processed locally on your device and is not recorded, stored, transmitted, or shared with any third party.
GNIS offers a one-time in-app purchase that unlocks the full version of the app, including additional game modes and content. All payments are processed by Apple through the App Store. GNIS does not receive, collect, store, or have access to payment card information, banking information, or other financial details.
GNIS uses RevenueCat to manage in-app purchases and purchase restoration. RevenueCat may process a unique app user identifier and purchase information in order to provide these services.
GNIS does not knowingly collect any data from children under the age of 13.
We may update this policy occasionally. Any changes will be reflected on this page with an updated date.
