Engineered for Absolute Privacy
Your career, voice, and code are sacred. We engineered offcuff.ai with a zero-retention, RAM-only architecture that makes data leaks technically impossible.
100% Invisibility at OS Level
Window hooks into the OS compositor directly (WDA_EXCLUDEFROMCAPTURE on Windows and CGWindowSharingType.none on macOS). Screen capture software cannot physically render the overlay pixels.
Volatile RAM-Only Buffer
Audio frames from speaker loopback and microphone exist strictly in volatile RAM ring buffers. As soon as transcription frames are processed, memory is wiped. Zero disk writes.
Microsoft SQL RLS & AES-256
Uploaded documents and resumes are indexed in private Microsoft SQL Server instances with Row-Level Security (RLS) and AES-256 encryption at rest. Delete any record permanently with 1 click.
The Ephemeral Data Flow Pipeline
How audio travels through offcuff.ai without ever touching persistent cloud storage.
Local Audio Loopback
CoreAudio or WASAPI taps speaker & mic audio. No external bot joins the call guest list.
RAM Ring Buffer
Audio is segmented into 16-bit PCM streaming buffers in volatile computer memory.
Encrypted Inference
Transcripts stream over TLS 1.3 to private dedicated inference clusters in under 84ms.
Immediate Memory Wipe
HUD displays the response. Raw audio buffers are zero-filled immediately. Nothing saved to disk.
Compliance & Regulatory Readiness
Annual audits covering security, confidentiality, and processing integrity.
Full data sovereignty rights, instant 1-click purge, and zero data selling guarantee.
Rigorous information security management systems governing all client operations.
Quarterly gray-box security evaluations conducted by independent cybersecurity firms.
