Privacy Policy & Zero Data Retention

Last Updated: August 2026 • Effective Date: Immediately

🔒 Zero Data Retention (ZDR) Guarantee

Fusion operates under a strict, verifiable Zero Data Retention (ZDR) standard across our edge gateways and compute infrastructure:

  • No Prompt Storage: We do not log, persist, or store the contents of your input prompts, uploaded code, or system instructions on any persistent disk storage.
  • No Completion Storage: Generated model outputs and streaming tokens are streamed directly to the client via memory buffers and are never saved.
  • No Model Training: Your data is never used to train, evaluate, fine-tune, or improve any artificial intelligence models, proprietary weights, or third-party datasets.
  • Volatile KV Prompt Caching: Cached prefixes reside strictly in volatile memory / high-speed GPU KV caches with automatic TTL expiration and cryptographic tenant isolation.

1. Information We Collect

We collect only the minimal metadata necessary to authenticate your API requests, enforce security quotas, and bill for token usage:

  • Account Identifiers: Email address and authentication tokens used to manage your account and billing.
  • Usage Metadata: Numerical token counts (prompt tokens, completion tokens, cached tokens), timestamp, model ID, and request duration for real-time metering and invoice generation.
  • Telemetry & Reliability: HTTP status codes, latency metrics, and error classifications to monitor uptime and network health.

2. How Inference Requests are Processed

When you send an API request to /v1/chat/completions:

  1. Edge Authentication: Your API key is validated in sub-millisecond edge memory via Cloudflare Workers.
  2. Encrypted Transport: The payload is transmitted over TLS 1.3 encrypted connections directly to our compute clusters.
  3. In-Memory Execution: The GPU cluster loads the weights, processes tokens in memory, and returns Server-Sent Events (SSE).
  4. Ephemeral Tear-Down: Once the stream terminates, all prompt context in the execution buffer is immediately purged.

3. Upstream Provider Compliance

Fusion routes requests only through compute partners, hardware providers, and decentralized shard networks that contractually adhere to Zero Data Retention and zero-training policies. We do not sell, rent, or monetize developer data to any third party.

4. Data Security & Encryption

We employ enterprise-grade security protocols, including end-to-end encryption in transit (HTTPS / TLS 1.3), strict CORS origin isolation, automated DDoS mitigation at the edge, and hashed API key storage.
