# Security and data responsibility Connector packages execute inside the host Node.js process and receive complete form submissions. Install only trusted connector packages and review upgrades before deployment. Keep database credentials in ignored local environment files or a secret manager. For PostgreSQL, use TLS for remote connections and grant a dedicated role only the schema and table privileges it needs. For SQLite, restrict access to the database file and its backups, and keep it outside publicly served directories. Connectors do not provide user authentication, application authorization, encryption-key management, backup policies, retention schedules, or regulatory controls. The application and storage owner must define and enforce those controls for the data being collected. Schema expressions execute according to the [Core trust model](/core/security). A storage connector does not sandbox schemas or make untrusted executable schema content safe. Report connector vulnerabilities privately through the security policy in the affected connector's GitHub repository. Do not disclose suspected vulnerabilities in a public issue.
