# Strata Storage

> Zero-dependency universal storage library and Capacitor plugin. One unified
> async/sync API across web, Android, and iOS for localStorage, IndexedDB,
> cookies, Cache API, SQLite, Preferences, and Keychain/Keystore — with built-in
> encryption (AES-GCM/CBC), compression, TTL expiration, a MongoDB-style query
> engine, cross-tab sync, integrity checksums, and disaster recovery. Optional
> React, Vue, and Angular bindings. MIT. Developed with love by the Strata
> Storage Team (maintained by Ahsan Mahmood).
