# Offline Sync

## Overview

Offline-first patterns for React Native using MMKV for fast local storage and React Query for cache persistence and mutation queuing.

## When to Use

- Storing data locally for offline access
- Queuing mutations when network unavailable
- Syncing queued mutations on reconnect
- Handling conflict resolution
