AI Prompt Enhancer respects user privacy. The extension operates entirely locally within your browser. All prompts, context, and enhancements are processed on your machine and never transmitted to any servers. If you optionally enable the BYOK (Bring Your Own Key) feature to use your own Gemini API key, only your chosen API key (which you provide) is stored encrypted in browser storage. No usage data is collected or sent externally. The extension does not track user behavior, collect analytics, or share any data with third parties.
