This trademark policy was prepared to help you understand how to use the Gumroad, Inc. trademarks, service marks and logos with Gumroad, Inc.'s Iffy software.
While some of our software is available under a free and open source software license, that copyright license does not include a license to use our trademark, and this Policy is intended to explain how to use our marks consistent with background law and community expectation.
This Policy covers:
- Our word trademarks and service marks: Iffy, Iffy Community Edition
- Our logos: The :/ iffy logo on iffy.com
This policy encompasses all trademarks and service marks, whether they are registered or not.
Whenever you use one of our marks, you must always do so in a way that does not mislead anyone about what they are getting and from whom. For example, you cannot say you are distributing the Gumroad, Inc. Iffy software when you're distributing a modified version of it, because recipients may not understand the differences between your modified versions and our own.
You also cannot use our logo on your website in a way that suggests that your website is an official website or that we endorse your website.
You can, though, say you like the Gumroad, Inc. Iffy software, that you participate in the Iffy community, that you are providing an unmodified version of the Iffy software.
You may not use or register our marks, or variations of them as part of your own trademark, service mark, domain name, company name, trade name, product name or service name.
Trademark law does not allow your use of names or trademarks that are too similar to ours. You therefore may not use an obvious variation of any of our marks or any phonetic equivalent, foreign language equivalent, takeoff, or abbreviation for a similar or compatible product or service. We would consider the following too similar to one of our Marks:
- MyIffy
- Iffy
When you redistribute an unmodified copy of our software -- the exact form in which we make it available -- you must retain the marks we have placed on the software to identify your redistribution.
If you distribute a modified version of our software, you must remove all of our logos from it. To assist you with this, we have removed our logos from our source trees, and include them only in our binaries.You may use our word marks, but not our logos, to truthfully describe the origin of the software that you are providing. For example, if the code you are distributing is a modification of our software, you may say, "This software is derived from the source code for Gumroad, Inc. Iffy software."
You may use the word marks, but not the logos, to truthfully describe the relationship between your software and ours. Any other use may imply that we have certified or approved your software. If you wish to use our logos, please contact us to discuss license terms.
If you wish to describe your product with reference to the Iffy software, here are the conditions under which you may do so. You may call your software XYZ (where XYZ is your product name) for Iffy only if:
- All versions of the Iffy software you deliver with your product are the exact binaries provided by us.
- You use the following legend in marketing materials or product descriptions: "Iffy is a trademark of Gumroad, Inc."
You must not offer a hosted or managed service using our marks. The operation of your service would have implications for the quality control represented by our trademark. If you wish to do this, you can only do so under a license from us. If you offer such a service under your own marks, you can only state that your service is built using the Iffy software, and you may not use our logo.
You can use the Word Marks as part of your user group name provided that:
- The main focus of the group is our software
- The group does not make a profit
- Any charge to attend meetings are to cover the cost of the venue, food and drink only
You are not authorized to conduct a conference using our marks.
You must not register any domain that includes our word marks or any variant or combination of them.
When you have the right to use our mark, here is how to display it.
The first or most prominent mention of a mark on a webpage, document, or documentation should be accompanied by a symbol indicating whether the mark is a registered trademark ("®") or an unregistered trademark ("™"). If you don't know which applies, contact us.
Place the following notice at the foot of the page where you have used the mark: "Iffy is a trademark of Gumroad, Inc."
Always use trademarks in their exact form with the correct spelling, neither abbreviated, hyphenated, or combined with any other word or words.
Unacceptable: Gumroad, Inc.-DB
Don't pluralize a trademark.
Unacceptable: I have seventeen Gumroad, Inc.s running in my lab.
Always use a trademark as an adjective modifying a noun.
Unacceptable: This is a Gumroad, Inc.
Acceptable: This is a Gumroad, Inc. software application.
You may not change any logo except to scale it. This means you may not add decorative elements, change the colors, change the proportions, distort it, add elements, or combine it with other logos.
However, when the context requires the use of black-and-white graphics and the logo is color, you may reproduce the logo in a manner that produces a black-and-white image.
