Terms & Conditions

Last updated: September 2026

The service

Mermaid Theme provides a free, browser-based tool for rendering and styling Mermaid diagrams. The service is provided “as is” without warranties of any kind.

Acceptable use

You may use this tool for any lawful purpose. You agree not to misuse the service, attempt to disrupt it, or use it to infringe on the rights of others.

Your content

All Mermaid code and diagrams you create remain yours. Because the tool runs entirely in your browser, we never take possession of, or responsibility for, your content.

Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the service, including loss of data. Keep your own copies of important diagrams.

Changes

We may update these terms from time to time. Continued use of the site after changes are posted constitutes acceptance of the updated terms.
