Privacy Policy for Hmmmmnm Diagram Generator

Last updated: September 2025

1. Overview

Hmmmmnm Diagram Generator is a Chrome Extension that allows users to create, encode, and render diagrams (Mermaid, PlantUML) with AI assistance.

2. Data Collection

This extension does not collect, store, or share any personal or sensitive user data. All diagram processing happens locally in your browser.

3. Third-Party Services

• Kroki: If you choose to render diagrams via Kroki (public or Docker), the diagram content is sent to that service, but no personal information is included.
• AI Providers: If you use AI features, the text you provide is sent to the selected provider (Google Gemini or OpenAI). You are responsible for ensuring your input does not contain sensitive personal information.

4. Local Storage

Extension settings (API key, server URL, model selection) are stored locally in your browser via localStorage. They are never transmitted to the developer.
