# DashReporter licence

Copyright © 2026 Matt Goddard. All rights reserved.

DashReporter is **source-available**, not open source. The source is published so that it can be
read and checked — the claim that your data never leaves your machine is only worth making if
someone can verify it — and the terms below are what allow it to stay readable.

## You may

- **Use it**, for anything, including commercially, at no cost.
- **Read, study and modify** the source, for yourself or inside your organisation.
- **Host your own copy**, including a modified one, for yourself or inside your organisation.
  A network that blocks external sites may leave this as the only way to use it at all, and that
  is a use this licence intends to permit.
- **Share the files it produces.** A `.drd` file, an exported report or a chart is yours. Nothing
  in this licence touches your data or anything you make with the tool.

## You may not

- **Offer it publicly as a service or product**, hosted or distributed, whether or not you charge
  and whether or not you modified it, without written permission.
- **Remove or alter the attribution**: the origin recorded in `.drd` files, the canonical link,
  the generator metadata, or the copyright notice.
- **Present it as your own work**, or use the DashReporter name to describe something you built.

## Attribution

If you host a copy anywhere others can reach it, say plainly on the page that it is DashReporter,
and link to <https://dashreporter.com/>. That is the whole of what is asked in return for a tool
that costs nothing and phones home never.

## No warranty, no liability

**PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO
EVENT SHALL THE AUTHOR BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION
OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE
OR OTHER DEALINGS IN THE SOFTWARE.**

This applies to the fullest extent permitted by law. Some jurisdictions do not allow certain
liabilities to be excluded; nothing here excludes what cannot lawfully be excluded.

**Check your numbers.** This is a tool for looking at data, not a system of record, and no
dashboard is a substitute for understanding the thing it describes.

## The name

No rights in the name DashReporter, or in any associated mark or logo, are granted by this
licence. Naming it as the source, as the attribution above asks, is not a use this restricts.

## If these terms are broken

The rights granted here end automatically if the terms are broken, and come back as soon as the
breach is put right. Nothing is forfeited permanently by an honest mistake that gets fixed.

## Third-party components

DuckDB-WASM and Apache Arrow are bundled under `web/vendor/` and remain under their own licences
(MIT and Apache-2.0 respectively). Those licences govern those components; this one does not
extend to them.

## Getting permission

The restriction above exists to stop a copy becoming the place people go, not to stop anyone
using this. If you want to do something it forbids, ask — the answer is often yes.

Licence version 1.0, 2026-08-24. A copy you hold stays under the version it came with; a later
version does not reach back and change terms you already have.
