End-user license agreement

Last updated 13 November 2026. This is a proprietary, source-available license, not an open-source grant. The complete text also ships as LICENSE.txt in each buyer package.

Grant

Upon payment and issuance of a signed license token, the operator grants you, the original buyer, a lifetime, non-exclusive, non-transferable right to use the licensed Fathom Terminal tree for your own internal purposes, including writing your own plugins.

Restrictions

You may not redistribute, publish, resell, or sublicense the source, the token, or a substantial derivative, and you may not sell a product that is a thin wrapper of this tree. You may not remove copyright notices, license checks, or buyer marks. You may not share the token.

License check

The engine verifies the token offline with a bundled public key at startup. There is no phone-home. A missing or invalid token prevents the desk from starting.

Audit and termination

If we have a good-faith reason to believe the tree or token has been redistributed, we may ask you to confirm that your copy is still under your control. We may terminate the license if these terms are breached. Termination does not refund the purchase price.

No warranty

The software is provided as-is, without warranty of any kind, including fitness for a particular purpose. We are not responsible for trading losses, downtime, or venue changes. This is not advice.
