Dyalog Basic Licence
You will be granted a Basic Licence when you accept the conditions and download a free copy of Dyalog. The Basic Licence allows APL users to have a copy of the latest Dyalog technology for personal or non-commercial use and experimentation and other Non-commercial Purposes only.
The Basic Licence is intended for use as a personal productivity tool in a general non-commercial environment, and you may not exercise any of the rights granted to you by the Basic Licence for any Commercial Purpose. This means that as long as you are not making or trying to make money from your use of the licensed work, you are OK. Common categories of non-commercial use include educational use, personal use, experimentational use, proof of concept use, participating in programming competitions for prizes, and just-for-fun use.
Support and Non-Commercial Use
Holders of Basic Licences can subscribe to the Dyalog Support Service (DSS), which offers users support, maintenance and upgrades.
“Non-commercial Purposes” means those purposes for which no fee, rate, charge, or other consideration is charged to any third party, or which is considered by Dyalog Ltd as a charitable, educational, or other not-for-profit purpose, and which is not otherwise considered a Commercial Purpose.
Note: If you want to distribute Dyalog with your work, you will need an appropriate Run-Time Licence. Holders of Basic Licences can distribute Dyalog with their work under the terms of the Royalty-Based Run-Time Licence, which will apply as the default run-time licence.
