Trademark Policy

The name "Diagrams.so" and the Diagrams.so logo are trademarks of RedHold LLC. This policy explains what you can do with them without asking and what needs written permission. The goal is simple: make honest community use easy, and stop uses that confuse people about what is and is not official.

1. Uses that are always fine

Truthful uses that do not imply we made, endorse, or operate your product:

• "Built with Diagrams.so", "powered by Diagrams.so", "works with Diagrams.so", in text, on your site, or in listings.
• Compatibility statements for integrations, such as "an MCP client for Diagrams.so" or "a plugin for the Diagrams.so API", as long as your own name comes first and ours describes compatibility.
• Community project names in the form "yourname-for-diagrams-so" or "X for Diagrams.so". The pattern makes clear the project is yours.
• Writing about us: articles, tutorials, talks, reviews, comparisons, and academic work.
• Linking to diagrams.so and using an unmodified logo as the link icon in an integrations or compatibility list.

2. Uses that need permission

• Using "diagrams-so", "diagrams_so", "diagramsso", or "Diagrams.so" as the name of your package, module, extension, or repository on npm, PyPI, or any registry. That namespace reads as official; use the "yourname-for-diagrams-so" pattern instead. Our official packages are @diagrams-so/* on npm and diagrams-so on PyPI.
• Putting our logo on modified builds or forks of our open-source code, or on any product we did not make.
• Names, domains, or social handles implying you are us or endorsed by us, including anything containing "official" or "certified" together with our marks.
• Using the marks on merchandise for sale, or in a way that is dishonest or misleading.
• Registering trademarks, company names, or domains confusingly similar to ours.

If you are unsure, ask legal@diagrams.so.

3. The code license is not a trademark license

Our MCP server and SDKs are licensed under Apache-2.0. That license expressly does not grant trademark rights: you may fork, modify, and redistribute the code, but the Diagrams.so name and logo do not come with it. Ship your fork under your own name with a truthful compatibility statement, such as "a fork of the Diagrams.so MCP server".

4. Logo usage

Where a permitted use includes our logo: use the files we publish, unmodified. No recoloring, distortion, effects, or combining it into your own logo. Keep clear space around it and do not make it the most prominent element of your page.

5. Third-party trademarks

Diagrams.so interoperates with products whose names belong to others, including Anthropic, OpenAI, Microsoft, Azure, AWS, Google Cloud, Oracle, Databricks, and draw.io. We use those names only to describe compatibility, and their appearance in our products implies no endorsement by or affiliation with those companies. Icons and logos available in our icon libraries remain the property of their respective owners. If you build on our SDKs, extend those companies the same courtesy we ask for our own marks.

6. Enforcement and changes

We may ask you to change a use that violates this policy, and we reserve all rights in our marks. Not enforcing in one case is not a waiver in others. To report misuse of our marks, or to raise a concern about our use of yours, email legal@diagrams.so.
