 **Battery optimization**: The feature uses throttled sensor updates (10Hz) and frame processing (30fps) to minimize battery impact while maintaining smooth scrolling.
 
+### 🛡️ Critical Data Loss Fix (MMKV Migration)
+**Fixed random data loss issues** where history, bookmarks, and downloads would occasionally disappear when closing and reopening the app.
+
+- **Root cause**: AsyncStorage has a 6MB limit on Android. When users accumulated large amounts of history and downloads, storage would fail silently, causing data loss on app restart.
+- **Solution**: Migrated from AsyncStorage to **MMKV** - a faster, more reliable storage solution without size limits.
+- **Zero data loss**: Seamless one-time migration automatically transfers all existing data (history, bookmarks, downloads) to the new storage on first app launch.
+- **Better reliability**: MMKV is significantly faster and has no practical storage limits, preventing future data loss issues.
