CommandEditor — Security & Compliance Last updated: 26 August 2026 Short version: your files are processed entirely inside your browser and are never uploaded, so most of the usual risk surface simply does not exist. 1. ARCHITECTURE — EVERYTHING RUNS ON YOUR DEVICE CommandEditor is a client-side application. Merging, editing, converting, OCR, signing, redaction, encryption and every other operation execute in your browser using JavaScript and WebAssembly. The website is served as static files from a CDN; there is no server that receives, processes, or stores your documents. The optional desktop app (Windows, macOS, Linux) runs the same engine fully offline. 2. DATA HANDLING — NO UPLOADS, VERIFIABLE Documents are never transmitted to CommandEditor. The built-in "Proof of No Upload" tool monitors outgoing network activity so you can confirm file bytes never leave the device. Small preferences (dark mode, recent file names) live only in your browser's local storage and can be cleared at any time. 3. CRYPTOGRAPHY Standard primitives via the browser Web Crypto API: AES-256-GCM (encryption), PBKDF2 (password-based key derivation), ECDSA P-256 (e-signatures), SHA-256 (integrity). Notarization uses the open OpenTimestamps standard, anchoring only a SHA-256 hash — never the document. 4. APPLICATION & TRANSPORT SECURITY HTTPS only with HSTS (preloaded); strict Content-Security-Policy; X-Frame-Options DENY and frame-ancestors 'none'; X-Content-Type-Options nosniff; restrictive Permissions-Policy; object-src 'none'. Untrusted HTML (converted files, AI output) is sanitized before rendering. No advertising or cross-site tracking cookies; only privacy-friendly cookieless aggregate analytics (see section 8). 5. DATA PROTECTION & GDPR No personal data collected on any server, no user accounts, no server-side logging of your files. Local processing supports data-minimization by design. Standard host request metadata (e.g. IP) may be logged for reliability/security and is never linked to document content, which never reaches the server. 6. HEALTHCARE (HIPAA) POSTURE PHI placed into CommandEditor is processed on your device and never received by CommandEditor. A Business Associate Agreement is not applicable, because CommandEditor is a client-side utility rather than a business associate handling your data. CommandEditor is not itself a certified or covered entity; whether a workflow is HIPAA-compliant depends on your environment and controls. 7. ENTERPRISE CONTROLS (NO CLOUD ACCOUNT REQUIRED) On-device controls that need no backend: policy presets, chain-of-custody log, per-recipient document fingerprinting for leak attribution, tamper-evident seals, and a downloadable cryptographic audit trail for signatures. 8. WHAT COMMANDEDITOR DELIBERATELY DOES NOT DO No advertising, no cross-site tracking, no account requirement, no server-side copies of your files, no transmission of document content to any third party (including for AI, which runs locally). 9.
