We’re always excited to see customers building off of Trello’s platform to make their own extensions and apps. As part of that process we want to make sure that folks don’t think that a third-party app is officially affiliated with Trello. We’ve created some guidelines to help clarify what is and isn’t okay when making your own apps.
Naming your app
Generally speaking, we encourage third-party app creators to use the “... for Trello” naming convention. For example, “ Scrum for Trello,” “Calendar for Trello,” or “Harvest for Trello.” This is usually a good way to make it clear what an extension does, while not implying that it’s made by Trello.
We ask that you include a disclaimer indicating that you’re not affiliated with Trello, such as:
We are not affiliated, associated, authorized, endorsed by or in any way officially connected to Trello, Inc. (www.trello.com).
The “Trello” in your app’s name should have a registered trademark symbol (®) next to it.
Names that are derivative of Trello’s own name are not permitted. Neither are names with “by Trello.” For example, “Huskello” or “Huskies by Trello” can’t be used. However, “Huskies for Trello” could be used.
If you have questions about your app’s name, feel free to contact Support directly.
Use Taco or the Trello logo for your application’s icon
Create a modified version of Taco or the Trello logo
Integrate Taco or the Trello logo into your logo
Change the logo colors, dimensions or add your own text/images
Check out our brand assets page for more info.
Please don’t include quotes from Trello founders or employees that imply that Trello endorses your product.
This article is intended as a quick overview of what is/isn’t okay when it comes to building third-party apps using Trello—if you have other questions or concerns, or just want to let the Trello team know about your app, we’d love to hear from you! Drop us a line using our contact form, and we’ll be in touch.
