Here's how the privacy-compliant data storage is implemented in the app:
// Local storage using AsyncStorage (no cloud sync)
import AsyncStorage from '@react-native-async-storage/async-storage';
// Storage keys for local data
const STORAGE_KEYS = {
HIGH_SCORE: 'tetris_high_score',
GAME_STATS: 'tetris_game_stats',
SETTINGS: 'tetris_settings',
ACHIEVEMENTS: 'tetris_achievements',
DAILY_CHALLENGE: 'tetris_daily_challenge'
};
// Saving high score locally
const saveHighScore = async (score) => {
try {
await AsyncStorage.setItem(STORAGE_KEYS.HIGH_SCORE, score.toString());
} catch (error) {
console.error('Failed to save high score locally:', error);
}
};
// Loading settings locally
const loadSettings = async () => {
try {
const settings = await AsyncStorage.getItem(STORAGE_KEYS.SETTINGS);
return settings ? JSON.parse(settings) : defaultSettings;
} catch (error) {
console.error('Failed to load settings:', error);
return defaultSettings;
}
};
Offline First: Game works completely offline
No Analytics: No tracking or analytics libraries
No Ads: No advertising networks that collect data
Local Leaderboards: High scores stored locally only
Optional Permissions: All permissions are optional and clearly explained
