Privacy Policy
21 (Le 21)
This Privacy Policy explains how 21 (Le 21) handles information when you use the app.
Overview
21 (Le 21) is a local multiplayer dice game. The app is designed to work without account creation and without collecting personal identity information for remote profiling.
Information We Process
- Game data you enter: player names, optional magic-number settings, match history, and leaderboard values.
- Gameplay telemetry for in-app features: dice outcomes and round statistics used to calculate scores and display game events.
- Technical interaction signals: shake/rub gestures used only to trigger dice rolls during gameplay.
How Data Is Used
- To run core gameplay logic, scoring, and tie-break mechanics.
- To save your game preferences and profile options on your device.
- To restore local leaderboard and configuration between app sessions.
Data Storage
App state is persisted locally on your device using Expo FileSystem storage. This may include game settings, saved profiles, and leaderboard values. This local data is not intended for sale and is not used for advertising.
Permissions
- Internet: used to load external 3D dice rendering assets.
- Accelerometer/Sensors: used for optional shake-to-roll gameplay input.
- Vibration: may be used to enhance gameplay feedback.
- Storage access (platform-dependent): used by runtime components for local file operations and compatibility.
Third-Party Services and Libraries
- UNPKG CDN and @3d-dice/dice-box: used to fetch 3D dice engine scripts and assets for rendering dice in an in-app WebView.
- Expo and React Native ecosystem libraries: used for app runtime, UI, navigation, and local device APIs.
No Firebase SDK, analytics SDK, ad SDK, or user authentication SDK was detected in the current app codebase.
Data Sharing
The app does not intentionally share your personal data with third parties for marketing. Data may still be processed by infrastructure involved in delivering third-party assets (e.g., content delivery networks) when those assets are requested by the app.
Your Choices
- You can choose whether to enable gameplay features like shake or rub controls.
- You can clear app data through your device settings to remove locally stored data.
Children's Privacy
21 (Le 21) does not knowingly collect personal information from children through account-based features.
Policy Updates
This Privacy Policy may be updated from time to time. Changes will be reflected on this page with an updated "Last updated" date.
