Last updated: March 16, 2026

At McQuizzy Inc. ("we", "us", or "our"), the security of your data is a top priority. This Security Policy describes the measures we take to protect your information when you use the McQuizzy website at mcquizzy.com (the "Service").

1. Infrastructure Security

We use industry-leading cloud infrastructure providers to host our Service. Our infrastructure includes:

  • Hosting: Our application is hosted on Railway with automatic scaling and redundancy.
  • Database: We use Supabase (built on PostgreSQL) with automated backups, encryption at rest, and row-level security.
  • CDN: Static assets are served through a content delivery network for performance and DDoS protection.
  • SSL/TLS: All data transmitted between your browser and our servers is encrypted using TLS 1.2 or higher.

2. Authentication and Access Control

  • Authentication: We use Clerk for authentication, providing secure sign-in with support for multi-factor authentication (MFA), social login, and passwordless authentication.
  • Session management: Sessions are securely managed with automatic expiration and token rotation.
  • Role-based access: Internal systems use role-based access control (RBAC) to ensure employees only access data necessary for their role.

3. Data Encryption

  • In transit: All data is encrypted in transit using TLS 1.2 or higher.
  • At rest: All data stored in our databases is encrypted at rest using AES-256 encryption.
  • Payment data: We use Stripe for payment processing. We never store credit card numbers, CVVs, or other sensitive payment data on our servers. Stripe is PCI DSS Level 1 certified.

4. Application Security

  • Input validation: All user inputs are validated and sanitized using Zod schemas to prevent injection attacks.
  • CSRF protection: Cross-site request forgery protections are implemented across the Service.
  • Rate limiting: API endpoints are rate-limited to prevent abuse and denial-of-service attacks.
