Terms of Service

1. Acceptance of Terms

By accessing or using the QuantumRand API, SDKs, dashboard, or any related services (collectively, the "Service") provided by Noel Innovations LLC, doing business as QuantumRand ("QuantumRand," "we," "us," or "our"), you agree to be bound by these Terms of Service ("Terms"). If you are using the Service on behalf of a company or organization, you represent that you have authority to bind that entity to these Terms.

If you do not agree to these Terms, do not use the Service.

2. Description of Service

QuantumRand provides a quantum entropy API that delivers random numbers and cryptographic primitives generated from a quantum entropy source — Qiskit Aer quantum circuit simulation by default, with quantum hardware backends available on paid plans when active. The Service includes:

• Core entropy endpoints (hex, integer, float, bytes, UUID)
• Financial primitives (transaction IDs, OTPs, nonces, keypairs, audit signatures)
• Industry-specific endpoints for fintech, gaming, healthcare, legal, cybersecurity, and IoT applications
• Audit logging and compliance dashboard
• SDKs for Python, JavaScript, and Go

The Service is provided on a subscription basis with a free tier and paid tiers as described at quantumrand.dev/pricing.

3. Third-Party Infrastructure Dependency

The Service relies on third-party quantum hardware providers to generate quantum entropy. QuantumRand does not operate quantum hardware directly.

3.1 Entropy Source Disclosure

All API responses include an entropy_source field indicating whether entropy was generated by quantum hardware ("quantum"), a blend of quantum and software entropy ("hybrid"), or software-based CSPRNG fallback ("fallback"). QuantumRand will never misrepresent the source of entropy delivered.

3.2 Service Availability

QuantumRand's ability to deliver quantum entropy depends on the availability of quantum hardware systems. During periods of quantum hardware unavailability, the Service may automatically fall back to hybrid or software-based entropy generation. QuantumRand is not liable for quantum hardware downtime or degraded availability.

3.3 No Affiliation

QuantumRand is not affiliated with, endorsed by, or officially partnered with any quantum hardware manufacturer. Use of quantum hardware is subject to the respective provider's terms of service.

4. Account Registration and API Keys

• You must provide accurate information when creating an account
• You are responsible for maintaining the security of your API key
• API keys must not be shared, published publicly, or committed to source control
• You must notify us immediately at security@quantumrand.dev if you suspect unauthorized use of your API key
• We reserve the right to revoke API keys that are compromised or used in violation of these Terms
• One free account per person or organization — creating multiple free accounts to circumvent rate limits is prohibited
