The following page outlines the general criteria for hardware products that bear the Respects Your Freedom hardware certification mark. However, each certified product carries with it contractual obligations that may differ from those listed on this page.
Companies interested in using the RYF certification mark should read the following criteria, and also contact firstname.lastname@example.org to learn more about the certification process. Qualifying hardware products include: computers, components for computers, devices that contain a reprogrammable computer, and devices meant to communicate digitally with a computer.
100% free software
All the product software must be free software. The product software includes all software that the seller includes in the product, provides with the product, recommends for use in conjunction with the product, and steers users towards installation in the product.
However, there is one exception for secondary embedded processors. The exception applies to software delivered inside auxiliary and low-level processors and FPGAs, within which software installation is not intended after the user obtains the product. This can include, for instance, microcode inside a processor, firmware built into an I/O device, or the gate pattern of an FPGA. The software in such secondary processors does not count as product software.
We want users to be able to upgrade and control the software at as many levels as possible. If and when free software becomes available for use on a certain secondary processor, we will expect certified products to adopt it within a reasonable period of time. This can be done in the next model of the product, if there is a new model within a reasonable period of time. If this is not done, we will eventually withdraw the certification.
The BIOS of a PC runs on the CPU, not on a separate secondary processor, so this exception does not apply to the BIOS.
By way of explanation, a general-purpose facility for installing other programs, with which the choice of programs to install comes directly from the user, is not considered to steer users toward anything in particular. However, if the product suggests using the facility to install certain programs, that is steering users towards those programs.
We maintain a license list that classifies common free and nonfree software licenses. It is not complete, so if you are interested in a certification and can't find the information you need, we would be happy to review the licenses of your product software and advise you on whether or not they are free software licenses.
Some device manufacturers include a CD-ROM with their product that has proprietary Windows drivers for the device. This is unacceptable because it does not meet the conditions above. The seller must either make those Windows drivers free software, or not include special Windows drivers.
User installation of modified software
The seller must give the user, along with the product software source code, the practical capability to install replacement software for any and all of the free software in the device. This means the product must have the requisite facilities to install software in the processors that run free software, and include adequate and sufficient documentation on how to use them. If software is required for this installation, it is considered part of the product software.
In addition to being free, all the product software must be buildable using 100% free software that's released to the public, on a 100% free operating system that is released to the public. In other words, a user should be able to rebuild all the product software, and replace everything on the programmable levels, using only readily available free software.
The product materials must say where to get the necessary build software. If some of this build software is included in an FSF-endorsed 100%-free GNU/Linux distribution (see our list), giving the name and URL of that distribution and the program or package names needed should suffice for the build software included in it.
Software for installation and maintenance
The programs needed to install and manage the product software must be released as free software. It is not required that they be capable of running on the product, but if they cannot, they should be able to run on most modern GNU/Linux systems.
No spying or back doors
Please be aware that we can't check products for spy features or back doors, but if we find out about any, we will drop our endorsement unless they are promptly removed.
Further, because spyware or a back door may take many forms, we are still working out precise criteria as we go along. The criteria stated below are our first attempts, and we may change them if we come across examples which they handle wrong.
"Spyware" is software that transmits or makes available to anyone other than the owner any information about the owner's or the product's identity, location, or activity except (1) when the owner asks to do so, (2) when inevitable due to communication protocols used, or (3) when required by law. In the case that 3 applies, the product should come with a prominent warning, plus a URL for where to obtain more information.
A "back door" is any functionality that gives remote control over any aspect of the device operation or its software. It is normal for computers to have facilities for updating software or for letting people log in remotely. These become back doors when they are enabled by default.
Confusion with other products
To prevent confusion among customers about exactly what product has been certified, any other products offered by the seller which are not certified by the FSF must be easily distinguishable from certified products: their names must not be similar, and their packaging must also not be similar.
Encumbered formats are those whose implementation is impeded by patents, interface copyrights, or other restrictions. If the device supports encumbered formats, it must also support free formats that serve the same general purpose.
For instance, MP3 is an encumbered format, because patent holders actively demand patent royalties from those who distribute players. Its general purpose is to serve as a lossy audio encoding format, providing a reasonable trade-off between sound quality and disk space. Ogg Vorbis is an unencumbered format and serves the same purpose. Thus, we could certify a Digital Audio Player (DAP) that plays MP3, provided it also plays Ogg Vorbis files just as well.
However, while the Free Lossless Audio Codec (FLAC) is unencumbered, it does not serve the same purpose as these other formats; instead, it serves to provide lossless sound compression at the cost of much more disk space. Thus, FLAC does not satisfy the criterion to make MP3 support acceptable, and we cannot certify a DAP that only supports MP3 and FLAC files.
The device may support formats that are hampered by Digital Restrictions Management (DRM), but it can only use free software to do so.
Any software patents the seller owns, that cover any aspect of the product software or its operation, must be licensed to all users who receive copies of any version of the software, in a way consistent with use and redistribution of that software as free software under the free software licenses that it carries.
Likewise for any patents that the company has obtained licenses to use in the product software.
Any generally useful technical documentation about the product, such as user or developer manuals, must be released under a free license.
Other misleading endorsements
Companies awarded RYF certification for a given product must not distribute any product-related materials with endorsements or badges to proprietary software, such as "Works with Windows" or "Made for Mac" badges, because these would give an appearance of legitimacy to those proprietary packages, and may make users think the product requires them. However, we don't object to clear factual statements informing the user that the product also works with specific proprietary operating systems.
Cooperation with FSF and GNU public relations
The seller must use FSF approved terminology for the FSF's activities and work in all statements and publications relating to the product. This includes product packaging and manuals, Web pages, marketing materials, and interviews about the product.
Specifically, the seller must use the term "GNU/Linux" for any reference to an entire operating system which includes GNU and Linux, not "Linux" or "Linux-based system" or "a system with the Linux kernel," or any other term that mentions "Linux" without "GNU." Likewise, the seller must talk about "free software" more prominently than "open source."
The FSF and the seller will jointly set up a bounty program to encourage the public to report any failure to follow these conditions, with a view to correcting the failures. In this program, the FSF will give a small reward to the first person to report any compliance problem in the product previously unknown to the FSF. The FSF will forward the reports to the seller.
Failing to meet these requirements at any point can result in immediate revocation of certification. However, if the failure was unintentional, we will look for a way to resolve the problem amicably by bringing the product into compliance with these terms.
