The Karuvigal Standard

Privacy by Architecture

We believe data sovereignty is a right, not a feature. Karuvigal executes logic client-side whenever possible. Your JSON data, password entropy seeds, and UUID generation processes happen within your browser's runtime, ensuring sensitive information never touches our servers.

Standards Compliance

Whether it's ISO/IEC 18004 for QR codes or RFC 4122 for UUIDs, our generators adhere strictly to technical specifications. We design for developers who require valid, interoperable outputs for their production systems.
