Our service uses Claude AI by Anthropic to generate diagrams based on your text descriptions. When you submit a request, your input is processed by Claude AI to create the diagram code and explanations.
Important Notice About AI: AI systems, including Claude, can occasionally produce inaccurate or misleading information (known as "hallucinations"). While we strive to provide accurate diagram generations, the AI may sometimes generate content that is incorrect, incomplete, or not precisely aligned with your intent. We recommend reviewing all generated diagrams for accuracy before using them in critical applications.
Your data processed by Claude AI is subject to Anthropic's privacy policy. For more information about how Anthropic handles data, please review their Privacy Policy.
3. Data Storage with Supabase
All generated diagrams and related information are stored using Supabase, a secure open-source database platform. Supabase provides enterprise-grade security with encryption at rest and in transit, ensuring your data is protected.
The data stored in Supabase includes:
- Your generated diagram code (Mermaid, PlantUML, etc.)
- Diagram metadata (creation date, diagram type, etc.)
- Shareable link identifiers
Supabase operates in accordance with industry-standard security practices and compliance requirements. For detailed information about Supabase's data protection measures, please refer to their Privacy Policy.
