You can sell for profit applications developed using the open source version of Tersus. For the license terms, see http://www.tersus.com/#Id=28.
The model of the applications (equivalent to "source code") is exposed to anyone with access to the relevant folder on the machine on which Tersus is deployed. Hiding or encrypting it will require special development in the Tersus platform, which we do not plan to develop in the near future.
