Mermaid App ("we," "our," or "us") operates the mermaid-app.com website and the Mermaid Diagram Renderer ChatGPT application (collectively, the "Service"). This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you use our Service.
We do not collect, store, or process any personal data. Our Service is designed with privacy as a core principle:
The Mermaid Diagram Renderer operates entirely within the ChatGPT environment. When you request a diagram:
All diagram processing occurs locally in your browser. We have no access to the content of your diagrams or your conversations with ChatGPT.
Our Service loads resources from the following third-party content delivery networks (CDNs):
These CDN providers may collect standard web server logs. Please refer to their respective privacy policies for more information.
Our Service operates within OpenAI's ChatGPT platform. Your interactions with ChatGPT are governed by OpenAI's privacy policy and terms of service. We recommend reviewing OpenAI's privacy practices at openai.com/privacy.
Since we do not collect or store any user data, there is no user data at risk on our systems. The Service communicates over HTTPS to ensure secure transmission of diagram code between ChatGPT and the rendering widget.
Our Service does not collect any personal information from anyone, including children under 13. The Service is accessed through ChatGPT, which has its own age requirements and policies.
Our Service is available internationally. Since we do not collect personal data, there are no cross-border data transfers to be concerned about regarding your personal information.
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. You are advised to review this Privacy Policy periodically for any changes.
