# VortX Trademark and Brand Use Policy

VortX is free and open-source software. The source code is licensed under the
GNU General Public License v3.0 (see `LICENSE`). This policy is separate from
that code license and governs the VortX name and logo, which are not licensed
under the GPL.

## What the GPL does and does not give you

The GPL gives you broad rights to use, study, modify, and redistribute the VortX
source code, including the right to fork it. The GPL does not grant any right to
use the VortX name, the VortX logo, or the VortX and VortX.TV brand to identify
your own build, product, service, or organization. Trademark rights are outside
the scope of the GPL, and this project reserves them.

This policy places no restriction on any freedom the GPL grants over the code. It
governs the name and the logo only.

## The name and the logo

The name VortX, the VortX logo, the VortX.TV name, and the `vortx.tv` identity
are unregistered trademarks of the VortX project. They may not be used in a way
that is likely to confuse people about the source of a product, or to suggest
affiliation with, sponsorship by, or endorsement by the VortX project when none
exists.

## If you fork VortX

You are welcome to fork the code. If you distribute your fork as a runnable app,
rename it. Specifically:

- Do change the app's display name (for example `CFBundleDisplayName` and
  `PRODUCT_NAME`) to a name that is not VortX and is not confusingly similar.
- Do change the application bundle identifier to your own namespace.
- Do replace the VortX app icon and logo with your own.
- Do keep the copyright notices, the GPL license, and the `THIRD-PARTY-NOTICES.md`
  attributions intact, as the GPL requires.
- You may state factually that your project is based on, or is a fork of, VortX.
  That descriptive reference is expressly permitted.
- Do not present your fork as the official VortX, as endorsed or approved by the
  VortX project, or use the VortX name or logo as the identity of your build,
  your developer account, your store listing, or your organization.

## Nominal use is always fine

You may use the word VortX truthfully to refer to this project, for example in
documentation, articles, comparisons, or a statement that your fork derives from
VortX. This policy exists to prevent confusion about source and endorsement, not
to stop anyone referring to the project by name.

## Questions and requests

If you are unsure whether a use is permitted, or you want to request permission,
open an issue and it will be answered.
