Your code is your own

The Contiki open source license does not require any code to be shared with others. If you use Contiki to develop code, your code is your own and you do not need to share it with anyone.

That said, we really appreciate code contributions to Contiki. If you want to contribute code to the Contiki project, however, we require this code to be covered by the same license as the rest of Contiki.
