Local storage and submissions

Included SQLite store

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

Code
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.
