Can I rebrand or sell or reuse or re-license or include Piwik in my product, company, or website?
Reusing Piwik in any way is allowed as long as you respect the GPL license. If your product, software, or website uses Piwik but all the code (including your modifications) stays within your company or server, you have the freedom to keep your code and not be bound to the GPL License. For example, you can change the header and footer to reflect your brand, change the colors, or add new features on your copy of Piwik. If you distribute a modified version of Piwik, or software that includes Piwik as a module, or develop a website for a customer/client that includes Piwik, you must give access to the code source and publish all the code under the GPL. Plugins Licenses: Individual components, libraries or plugins may be available for reuse under a different license. Please refer to the LEGALNOTICE file included in the distribution. You may want to learn more about the GPL License and look at the GPL FAQ. As well as respecting the GPL license, you must also reuse the word Piwik with care. P
