🛡️ Multi-AI File Paster - Security Policy

Chrome Extension Security Framework

Repository	Multi-AI File Paster
Lead Developer	Joseph Matino
Scrum Master	Majok Deng
Company	WekTurbo Designs - Hostwek LTD

Multi-AI File Paster applies layered security practices for Chrome extension development, ensuring user privacy and data protection across supported AI platforms (ChatGPT, Claude, Gemini, DeepSeek, Grok).

Absolute Privacy Guarantees:

• ❌ Zero Data Transmission: User content never leaves the local device under any circumstances
• ❌ No Server Infrastructure: Extension operates entirely client-side with no backend services
• ❌ No Content Persistence: All text processing is ephemeral - data is immediately discarded after processing
• ❌ No Personal Data Collection: Zero collection of URLs, browsing patterns, personal information, or user identifiers
• ❌ No Third-Party Services: No external APIs, tracking services, or data sharing with third parties
• ❌ No Cross-Site Tracking: Extension operates in isolated contexts per AI platform

Security-by-Design Implementation:

• ✅ On-Device Processing: All language detection, file creation, and content analysis happens locally
• ✅ Opt-In Telemetry: Anonymous usage statistics (file count, error rates) - completely optional and user-controlled
• ✅ Open Source Transparency: Complete codebase available for security auditing and verification
• ✅ Minimal Permission Model: Requests only essential Chrome extension permissions required for functionality
• ✅ Sandboxed Execution: Operates within Chrome's secure extension sandbox environment
• ✅ Content Security Policy: Strict CSP implementation prevents code injection and XSS attacks
