The Personal License
The world of licensing can be tricky and often confusing, so allow me to break it down as briefly as I possibly can.
Personal use – Everything under the personal license may not be used for commercial projects. A commercial project includes anything where either party involved gains monetary value from the work produced (read exceptions). Fonts may not be modified, distributed to a third party, embedded as a webfont, or embedded within a mobile app.
Student Use – You may use products under the personal license to complete student work such as school assignments and self-initiated projects, as long as it still falls under the uses outlined above.
Exceptions – Unlike most other personal use licenses, you can, in fact, sell your creations. However, there are restrictions. For example – you can design and sell greeting cards (for Birthdays, Christmas, etc) and sell them to a small group of people (family, friends, and friends of friends but not customers or clients). I do not consider this kind of small-scale work commercial. The price you are selling for is extremely low and it’s mainly paid as a token of gratitude. The same would apply for if you were to create an invitation for a friends wedding or a local charity. However, if you are advertising your services and start working with clients and/or customers, this is the moment things go commercial and you would need to upgrade your license.
