Licensee: The individual or entity that purchased the subscription ("you")

2. Proprietary Components

The following Atlas components are proprietary and are licensed, not sold, under this Agreement:

• — The training pipeline (train.py, generate_data.py)
• — The verifier bridge (bridge.py)
• — The licence key generator (keygen.py)

The open-core shell (ingest pipeline, MCP server, call graph walker, model architecture definition, CLI) is separately licensed under the Apache 2.0 licence and is NOT subject to this Agreement.

3. Licence Grant

Subject to your active paid subscription and compliance with this Agreement, we grant you a personal, non-exclusive, non-transferable, non-sublicensable licence to install and use the proprietary components on machines you own or control for your own internal development and commercial work.

4. Restrictions

You must not:

• 1. Redistribute the proprietary model weights or any portion of them
• 2. Reverse-engineer the weights, training pipeline, or verifier bridge
• 3. Extract training data or attempt to reproduce the training process from the weights
• 4. Sub-license the proprietary components to any third party
• 5. Share your licence key beyond your purchased seat count
• 6. Build a competing product that replicates Atlas's core functionality using knowledge derived from the proprietary components and offers it to third parties
• 7. Circumvent the licence enforcement mechanism
• 8. Use the proprietary components after your subscription has expired or been cancelled

5. Delivery

Proprietary components are delivered via secure download from our licence server (/v1/weights/) authenticated by your licence key. You are responsible for keeping your licence key confidential.

6. Updates

While your subscription is active, you are entitled to all updates to the proprietary components released during your subscription period. Updates do not reset the subscription term.

7. Ownership

All intellectual property rights in the proprietary components remain exclusively with Petrus Horn trading as Horn Software Architects. Nothing in this Agreement transfers ownership.

8. Term and Termination

• — You become insolvent or enter into bankruptcy proceedings

On termination, you must delete all copies of the proprietary components from your machines.

The proprietary components are provided "AS IS" without warranty of any kind, express or implied. We do not warrant that they will be error-free, accurate, or fit for any particular purpose.

10. Limitation of Liability

To the maximum extent permitted by South African law, our total liability for any claim under this Agreement is limited to the subscription fees you paid us in the 12 months preceding the claim.

We are not liable for indirect, incidental, consequential, or punitive damages, or for loss of profits, data, or business opportunities.
