Privacy Lab: Data Security in Pure DSD Batcher

🔐 All-Offline Privacy Architecture

In an era of ubiquitous digital surveillance, we firmly believe that your music taste and collection habits are deeply personal data. Efficient Lab has established a “Privacy-First” foundation from day one.

🛡 Core Mandates

  1. Local-Only Processing

    • All SACD ISO extraction and audio conversion are executed exclusively on your local machine.
    • We do not rent cloud transcoding servers, and your audio streams are never transmitted remotely.
  2. Zero Fingerprint Upload

    • While we support automated analysis, all feature comparisons occur within your local database.
    • Even when fetching album art, we use anonymized requests to prevent linking your IP to specific tracks.
  3. Transparency & Auditability

    • The core sacd-extract logic utilizes open-source components, keeping the codebase transparent and verifiable by the community.

🧱 Technical Fortification

  • 🔒 Sandboxed Mode: Strictly limited network permissions and file access on macOS.
  • 🔒 No Analytics: No third-party tracking (Firebase, Flurry, etc.). Your usage patterns are yours alone.

“Privacy is not an optional feature; it is a fundamental dignity for every audiophile.”
