# Commercial use

KILN is licensed under the **PolyForm Noncommercial License 1.0.0**. That licence covers
noncommercial use. Commercial use needs a written licence from the author.

This page says what counts, and how to ask. It is a summary, not the licence.

---

## Does this affect me?

| What you do | Covered by the free licence? |
|---|---|
| Learn from it, read the source, run the tests | yes |
| Build an app for yourself, your family, a friend | yes |
| Build an app for a charity or a research project, unpaid | yes |
| Teach with it, write about it, demo it | yes |
| Fork it and keep your fork noncommercial | yes |
| Build an app you sell, or bundle into something you sell | no |
| Use it inside a company, for that company's work | no |
| Ship a generated app to a client | yes — the app is yours; the compiler is not |
| Offer paid development, where KILN is part of how you deliver | no |
| Host it as a paid service | no |

If you are unsure which column you are in, ask. A one-line email costs nothing and an
assumption costs a lot.

## What you actually get

There are two editions, and exactly one difference that matters inside a generated app.
The full table is in [`LICENSING.md`](LICENSING.md).

| Edition | Sponsor and author block | Features |
|---|---|---|
| Personal (free) | yes, in the app's About panel | all 14 |
| Commercial (paid) | no — one line, "Built with KILN" | all 14, unlocked |

## What a commercial licence looks like

There is no price list, because the right terms depend on what you are doing. In practice
a commercial licence is a short written agreement covering:

| Term | Typical shape |
|---|---|
| Scope | which products, which teams, how many seats |
| Term | annual, or perpetual with a support window |
| Support | none, best-effort, or a named response window |
| Attribution | whether "built with KILN" must appear |
| Redistribution | whether you may ship the compiler to your customers |

## How to ask

Email **sohilmomin2000@gmail.com** with the subject `KILN commercial`, and include:

1. Who you are and what the organisation does.
2. What you want to build with it.
3. Whether the compiler ships to customers, or only the generated apps.
4. Roughly how many people would use it.

You will get an answer, a price if there is one, and no pressure.

## What you never need to ask about

Applications you generate are yours. Selling an app you built with KILN is governed by
the terms in [`TERMS.md`](TERMS.md) section 2 — the free licence covers the compiler, and
your own work is your own.
