GRAVITON 3D DOMINO

Last updated: April 2026

Overview

Graviton 3D Domino is a motion-based game developed by Tsook Nir LTD. This policy explains what information the app uses, stores, or transmits. We do not ask for your name, email, phone number, or any other personally identifying information.

Anonymous Authentication

To enable online multiplayer features, the app signs in to Firebase Authentication anonymously. This creates a random identifier that is not tied to your Apple ID, email, or any personal detail. No account or password is ever required.

Online Multiplayer Data

When you use online features (Team or Race modes), the following data is sent to our Firebase Realtime Database:

• Player nickname — a label you choose for yourself within the app. It is not verified and does not need to match your real name.
• Player emoji — the emoji you pick to represent yourself.
• Room code — a short code used to connect players in the same match.
• Game results — completion time, error count, and level, linked to the nicknames of participating players.

Room data is cleared automatically when a match ends. Top results may be retained in a leaderboard for the corresponding level, associated only with the nicknames entered by players.

Advertising

Graviton 3D Domino displays advertisements served by Google AdMob. Depending on your choice in the iOS App Tracking Transparency prompt, AdMob may access the Advertising Identifier (IDFA) to personalize ads. If you decline, non-personalized ads are shown instead. For details on AdMob's data practices, see Google's privacy policy at policies.google.com/privacy.

Motion Sensors

The app uses your device's motion sensors (gyroscope and accelerometer) to control gameplay. This data is processed on your device in real time and is never stored or transmitted.

Local Storage

Settings, your chosen nickname and emoji, personal best times, and local statistics are stored only on your device.

Third Parties

The app integrates the following services:

• Firebase Authentication (anonymous sign-in)
• Firebase Realtime Database (online multiplayer and leaderboards)
• Google AdMob (advertising)

No other third-party analytics, tracking, or marketing SDKs are used.

Children

The app is not directed at children under 13. Because no personally identifying information is collected, no such information is knowingly received from children.

Data Deletion

Uninstalling the app removes all local data from your device. Active room data in Firebase is removed automatically when a match ends. If you wish to request removal of your nickname from any retained leaderboard entry, contact us at the email below.
