1. Overview & Data Controller Identification
At Sophia Platform, privacy and data sovereignty are foundational to our architectural design.

2. Enterprise AI Data Privacy Pledge — Zero Model Training
We firmly pledge that NONE of your business data, prompts, Brand Voice profiles, uploaded RAG knowledge documents, voice recordings, or translation memory files are ever used to train, retrain, or fine-tune public foundation AI models (including OpenAI, Anthropic Claude, Google Gemini, DeepSeek, or open-source weights).
- Commercial Enterprise Terms with AI Providers: All upstream API drivers communicate via dedicated commercial zero-data-retention enterprise agreements with model vendors.
- Cloudflare Edge Zero-Retention: Inference prompts stream in real-time through Cloudflare Workers volatile memory. Raw prompt payloads are never logged to persistent disks or observability telemetry.
- Tenant Isolation: Vector embeddings in Cloudflare Vectorize and knowledge chunks in Cloudflare D1 are strictly isolated by
workspace_idwith row-level security.
3. Categories of Data We Collect
We collect only the minimum personal data strictly necessary to provision and maintain your account:
- Identity & Account Data: Name, business email address, company name, workspace profile, and cryptographic password hashes (hashed using Web Crypto PBKDF2 with 100,000 iterations and unique 16-byte salt).
- Financial & Transaction Data: Billing contact details, Stripe customer identifiers, subscription tier, and double-entry credit ledger transaction entries. We never store raw credit card numbers.
- BYOK (Bring Your Own Key) Credentials: When you provide your own provider API keys, they are encrypted using hardware-level AES-256-GCM before storage in our KV namespace.
- Telemetry & Usage Data: Anonymized request counts, token usage statistics, IP address (for rate limiting and DDoS mitigation only, discarded automatically), and response latency.
