1. Executive Summary & Zero-Retention Model

Stanza Infrastructure operates a portfolio of high-velocity microservices running on Cloudflare Workers global Anycast edge isolates across 330+ data centers. Every microservice operates under a strict Zero Data Retention ($f(x)=y$) Ephemeral Compute Architecture.

• 0 Bytes of Request Payloads Stored: Inbound transactional data exists solely in transient V8 isolate RAM for the milliseconds required to compute arithmetic transformations, after which it is immediately garbage collected.
• 0 Database Writes for Payload Processing: No relational databases, document stores, or S3/R2 storage buckets are attached to hot payload pipelines.
• 0 External Subrequests: Processing is 100% deterministic pure compute. The worker cannot leak data through third-party outbound network calls.

2. Cryptography & Data in Transit

All network communication strictly mandates TLS 1.3 encryption with strict modern AEAD cipher suites (TLS_AES_128_GCM_SHA256, TLS_CHACHA20_POLY1305_SHA256). HTTP Strict Transport Security (HSTS) is enforced with 1-year preloading.

Authentication uses SHA-256 constant-time XOR folding to prevent side-channel timing attacks across all platform keys and RapidAPI proxy secrets.

3. HIPAA PHI & GDPR DPA Compliance Status

Not yet HIPAA compliant — do not route live PHI through the platform. Transient in-memory processing of ANSI X12 837 claims or 835 remittances avoids persistent storage by design, but the formal HIPAA compliance program (risk assessment, BAA execution, third-party audit) is still in progress. Process only synthetic, test, or de-identified payloads until compliance is announced here.

European Union data sovereignty is supported via Anycast routing executing directly in European Union Cloudflare data centers (Frankfurt, Paris, Amsterdam). A GDPR Article 28 DPA is in progress — contact us for current status before routing EU personal data.

4. Infrastructure Resilience & SLA Commitment

All micro-APIs carry a contractually backed 99.9% Uptime Service Level Agreement backed by Cloudflare's Anycast network. Denial of Service (DDoS) protection absorbs multi-terabit volumetric traffic before it reaches compute isolates.
