Extensibility

Helipal is intentionally designed to accommodate extensions. Developers can create plugins that add new features or modify existing ones. The plugin system uses a declarative manifest file that describes required dependencies, configuration options, and entry points. Extensions are distributed through the Helipal Plugin Marketplace, which maintains a registry of vetted packages.

Security and Compliance

The platform incorporates role-based access control (RBAC), two-factor authentication (2FA), and end-to-end encryption for data in transit. Regular security audits are conducted by external firms, and the system complies with major privacy regulations, including GDPR, FERPA, and the California Consumer Privacy Act (CCPA). All personal data are stored in encrypted form at rest, and audit logs capture user actions for compliance verification.
