Infrastructure

System Information

Skill Focus Lab runs on Cloudflare's global edge network. Here's how our infrastructure works.

Infrastructure Stack

Cloudflare Workers

Edge compute — requests handled at the nearest of 300+ global locations

Cloudflare D1

SQLite database replicated across Cloudflare's edge

Stripe

PCI DSS Level 1 certified payment processing

OpenAI GPT-4o-mini

AI coaching via API — data not used for model training

Security Measures

TLS 1.3 encryption on all traffic (HSTS enforced)
PBKDF2 password hashing with unique salts
CSRF protection on all state-changing requests
Cloudflare WAF and DDoS protection
API rate limiting (60 req/min per IP)
Content Security Policy with per-request nonces

Report an Issue

If you experience a service disruption or security concern:

General issues: [email protected] or use the AI support chat

Security vulnerabilities: [email protected] — we acknowledge reports within 48 hours

Cloudflare Workers provide built-in redundancy — if one edge node fails, traffic routes to the next closest. We do not currently offer a contractual SLA. For Cloudflare's own infrastructure status, visit cloudflarestatus.com.
