Using External Trademarks
This page documents how to use external trademarks within KDE software and websites, i.e. trademarks not owned by KDE e.V. or the applications developer. It is important for the KDE community to respect other entities trademarks both because we expect other entities to respect our trademarks and because there can be legal and financial consequences for committing "trademark piracy".
What Is A Trademark?
- You must not modify the logo or name or slogan in any way, this includes for example giving a logo an Oxygen look, or changing the color.
- You must not use the name as a verb or a plural or abbreviate it.
- You must not use the logo instead of the name in the middle of a sentence.
- You must not use the name in any way that suggests you are the owner or have a particular relationship with the owner.
These are example terms only for illustrative purposes, you must check the actual terms that apply to the trademark you wish to use.
This section documents the best practices for trademark use as recommended by the KDE Community.
- Never use a trademark name in a library or application name as this could be seen as passing-off, e.g. a library called "libgoogle" or an app called "Facebook Chat" are not acceptable.
Commonly used Trademarks
- Skype expressly forbids the use of their logos under any circumstances unless you have written permission from them to do so.
- The one exception allowed is to show the Skype logo on your business card or advertising next to your Skype address. It is not recommended to try use this exception in an address-book app.

Each logo and badge also has extra terms attached, you must click-through the required logo and usage type to read the specific terms:
- The "f" logo for use on the web https://www.facebookbrand.com/guidelines?asset=2&media=1,2,3&platform=0
Generally the terms are:
- Facebook allows use of the "f" logo only, not the "facebook" logo.
- You must no modify the logos in anyway, other than to resize them.
- You can only use the "f" logo next to a factual text describing the use, e.g. "Chat using Facebook", or side-by-side with other social media buttons, e.g. in a "Share" dialog next to Twitter and G+.
- You can only use the "Like" logo to Like something on Facebook.
