License & acknowledgements

1. Product license

ATARS — the application, its brand name, logo and design — is the proprietary work of its developer, Priyanshu Kumar. All rights reserved. No part of the ATARS branding or proprietary code may be copied, republished or resold without written permission.

Three editions ship, under two licences:

• Desktop application — whether installed from ATARS-Setup.exe or from the Microsoft Store, use is governed by the End-User License Agreement shown at installation, together with the Terms of Service. Store installs are additionally subject to the Microsoft Standard Application License Terms.
• Terminal edition (pip install atars) — governed by the LICENCE.txt file inside the package, not by the desktop EULA. It is proprietary software published at no charge — it is not open-source. You may install and run it on any number of machines, for any purpose including commercial, with no fee and no account; everything it produces is yours; and you may pass the package on unmodified and in full, with the licence travelling with it. You may not modify it, republish it under another name, or resell it.
