# Velxio — Commercial License

**Copyright (C) 2025 David Montero Crespo**

## What is the Commercial License?

Velxio is dual-licensed:

- **AGPLv3** (see [LICENSE](LICENSE)) — free for everyone, including commercial use,
  as long as you comply with the AGPLv3 copyleft terms (i.e., any modifications or
  derivative works you distribute or run on a network server must also be released
  under AGPLv3).

- **Commercial License** (this document) — grants you the right to use, modify, and
  integrate Velxio into a proprietary / closed-source product or service **without**
  the AGPLv3 source-disclosure obligation. You pay once (or on a subscription basis)
  and keep your code private.

## Who needs a Commercial License?

You need a Commercial License if **any** of the following apply:

| Scenario | Needs Commercial License? |
|----------|--------------------------|
| Personal projects, learning, research | ❌ AGPLv3 is free |
| Open-source projects released under AGPLv3 | ❌ AGPLv3 is free |
| SaaS / web app where you keep your source private | ✅ Yes |
| Embedding Velxio in a commercial closed-source desktop app | ✅ Yes |
| Internal corporate tool where source is not shared with users | ✅ Yes |
| White-labeling or rebranding Velxio for clients | ✅ Yes |

## What the Commercial License grants you

- The right to use, modify, and distribute Velxio as part of a proprietary product.
- Exemption from the AGPLv3 network-copyleft clause — you do **not** need to
  release your product's source code.
- Permission to keep modifications private.
- One year of email support (depending on the tier agreed).
