Terms of Use

Last updated: June 13, 2026

By using Diagramgen you agree to these terms. If you do not agree, please do not use the tool.

The service

Diagramgen is a free tool that renders diagrams from text in your browser. It is provided free of charge, with no account required and no watermark on exports.

Provided “as is”

The tool is provided “as is”, without warranty of any kind. We do not guarantee that rendering will be error-free or available without interruption. The rendering engine is loaded from a third-party public CDN that we do not control.

Your content

You are responsible for the text and diagrams you create. Because everything is processed locally in your browser, your content is never sent to us — and we accept no responsibility for it. Do not use the tool for any unlawful purpose.

Limitation of liability

To the maximum extent permitted by law, we are not liable for any loss or damage arising from the use of, or inability to use, this tool — including any loss of data or diagrams.

Changes

We may update these terms from time to time. Continued use after a change means you accept the updated terms.
