What User Data We Collect
An exhaustive transparency breakdown proving zero off-device egress for all conversational, multimodal, and local system telemetry.
Comprehensive Data Collection & Residency Matrix
Every data category within the SIFRA ecosystem is handled under strict residency controls:
| Data Category | Local Processing | Local Storage | Cloud / Off-Device | Retention |
|---|---|---|---|---|
| Prompts & AI Chats | Local CPU / Vulkan GPU | Local SQLite (`/data/`) | 0 Bytes (Never Sent) | User Controlled |
| PDFs, Code & Docs | Local Parser & RAG | Local SQLite Embeddings | 0 Bytes (Never Sent) | User Controlled |
| Images & Video Keyframes | Local Multimodal Engine | Temporary Local Cache | 0 Bytes (Never Sent) | Immediate Purge |
| Microphone Audio & STT | Local Neural STT Engine | In-Memory Buffer Only | 0 Bytes (Never Sent) | Zero Retention |
| Hardware Telemetry (CPU/GPU) | Local Telemetry Daemon | In-Memory HUD Display | 0 Bytes (Never Sent) | Real-Time Only |
| Web Search Queries | Search Aggregator | Temporary Context | Anonymous Query (No User ID) | Session Only |
| Account & Machine Seat | License Verification | Local License File | Email & HWID Hash | Active Subscription |
| Contact Form Submissions | Edge Worker API | N/A (Web Form) | Name, Email, Message | 90 Days Auto-Purge |
Independent Network Verification Guide
SIFRA is designed to be auditable. We encourage security engineers, enterprise auditors, and privacy researchers to verify our zero-egress architecture using independent network inspection tools:
sudo tcpdump -i any -n "not port 53 and (dst host not 127.0.0.1)"
Notice that while SIFRA processes multi-page PDF documents, executes complex chain-of-thought mathematical reasoning, or performs speech-to-text dictation, zero packets depart your network interface. Core intelligence runs entirely within local host memory.
