# Local storage and submissions

<PageBadges />

## Included SQLite store

The starter saves structured submitted records with `expo-sqlite`. Configure or disable it through
the `storage` block in `form0.config.js`:

```js
storage: {
  enabled: true,
  databaseName: "form0.db",
  tableName: "form0_submissions",
  debug: false,
}
```

The database lives in the platform-specific application sandbox. Each submission is inserted with
record metadata and the complete structured record as JSON. The included debug controls can list
or clear records when `debug` is enabled.

## Persistence is not synchronization

This store provides on-device persistence only. It does not upload records, retry requests, resolve
conflicts, encrypt exports, or define retention and deletion policy. Applications must design those
behaviors for their data and threat model. Treat database backups and exported files as sensitive
user data.

The Node.js `form0-connector-pg` and `form0-connector-sqlite` packages do not run in React Native.
Send remote submissions through an authenticated application API; do not embed database credentials
in a mobile application.
