Security & Privacy

API Key Security

Following industry best practices from Codefinity and Medium security guides:

• Session Storage Only: API keys stored in browser sessionStorage (cleared when browser closes)
• No Server Transmission: Keys never sent to our servers - all processing happens in your browser
• Format Validation: Validates OpenAI API key format before acceptance
• Security Warnings: Clear notifications about key handling best practices
• Easy Key Management: Simple buttons to change or clear stored keys

Privacy Protection

• No data collection or analytics
• No server-side storage of questions or responses
• All processing happens locally in your browser
• API calls go directly from your browser to OpenAI
