# NPD — Not Permissive Distribution License

## Version 1.0.1

Copyright (c) 2026 JustQuirk

## 1. Definitions

For the purposes of this license:

* **"Software"** means the original software, mod, source code, compiled files, assets, and associated materials distributed under this license.
* **"Original Author"** means JustQuirk.
* **"Fork"** means any modified, adapted, or derivative version of the Software.
* **"Distributor"** means any person or organization that distributes, publishes, uploads, or otherwise makes the Software or a Fork available to others.
* **"Permitted Platforms"** means **Modrinth and CurseForge**, along with any additional platform later designated in writing by the Original Author under Section 4.

---

## 2. Permissions

Permission is hereby granted to any person obtaining a copy of the Software to:

* Use the Software for personal, educational, or non-commercial purposes.
* View and study the source code.
* Modify the source code.
* Create Forks and derivative works.
* Create private modifications for personal use.
* Redistribute modified versions of the Software, subject to this license.
* Include the Software in free modpacks and collections, subject to this license.
* Rename a Fork and give it its own branding, provided that it does not falsely represent itself as the official Software.
* Distribute the Software or a Fork through the Permitted Platforms, subject to the requirements of this license.

These permissions are conditional upon compliance with all restrictions in this license.

---

## 3. Fork Requirements

Any publicly distributed Fork must:

1. Clearly identify itself as a Fork or derivative of the original Software.
2. Give clear and visible credit to **JustQuirk** as the original author.
3. Include a copy of this license or a clear reference to the NPD License.
4. Provide a link or other clear reference to the original project where technically and practically possible.
5. Not falsely claim to be the official version.
6. Not remove or obscure the original attribution.
7. Not imply that JustQuirk endorses or maintains the Fork unless explicit permission has been granted.

Forks may use different names, branding, version numbers, and additional features.

---

## 4. Permitted Distribution Platforms

The Software and Forks may be publicly distributed **only through**:

* **Modrinth**
* **CurseForge**

Distribution through these platforms is permitted provided that all other terms of this license are followed.

Uploading the Software or a Fork to Modrinth or CurseForge does **not** grant permission to simultaneously distribute the same Software or Fork through unauthorized platforms.

The copyright holder may designate additional Permitted Platforms at their discretion by publishing a written notice (for example, on the official project page or repository). Doing so does not require a new version of this license and applies immediately to all versions of the Software and Forks distributed under this license, unless the notice states otherwise.

---

## 5. Commercial Distribution

Commercial distribution is permitted **only through the official monetization mechanisms provided by Modrinth or CurseForge**, where applicable.

Nothing in this license permits a person to directly sell, paywall, or otherwise commercially distribute the Software or a Fork outside those platforms.

Permitted platform revenue may include revenue generated through the platform itself, provided that the Software or Fork remains freely accessible to users in accordance with the platform's own rules and this license.

---

## 6. Prohibited Distribution and Monetization

You may **not**:

* Sell the Software directly.
* Sell a Fork directly.
* Charge users for downloading the Software.
* Charge users for downloading a Fork.
* Put the Software behind a paywall.
* Put a Fork behind a paywall.
* Require payment to obtain the Software.
* Require payment to obtain a Fork.
* Distribute the Software exclusively to paying supporters.
* Distribute a Fork exclusively to paying supporters.
* Sell access to the Software through Patreon, Ko-fi, memberships, subscriptions, or similar services.
* Sell access to a Fork through Patreon, Ko-fi, memberships, subscriptions, or similar services.
* Monetize distribution through a third-party platform other than a Permitted Platform.
* Sell the Software as part of a paid software package.
* Sell the Software as part of a paid mod collection.
* Sell a Fork as part of a paid software package.
* Sell a Fork as part of a paid mod collection.
* Charge money specifically and exclusively for access to the Software or Fork through a website, Discord server, launcher, repository, or other service, where the Software or Fork itself is not otherwise freely available through that service.
* Use donations, memberships, subscriptions, or similar payments as a condition for receiving the Software or Fork.
* Circumvent the platform restrictions of this license through mirrors, alternate download links, file-hosting services, or other distribution methods.
* Claim ownership of the original Software or its original source code.
* Remove the required attribution or license from a distributed copy.

---

## 7. Modpacks and Collections

The Software and Forks may be included in **free modpacks and collections**.

The following conditions apply:

* The modpack must not charge specifically for access to the Software.
* The Software must remain subject to this license.
* The original author must be credited where reasonably practical.
* The Software must not be separately paywalled inside the modpack.
* A paid modpack or collection may not include the Software if payment is required specifically to obtain access to the Software.

Nothing in this section grants permission to sell or separately monetize the Software.

---

## 8. Distribution Outside Permitted Platforms

Public distribution of the Software or a Fork outside the Permitted Platforms is prohibited.

This includes, but is not limited to:

* Personal download websites.
* File-hosting services.
* GitHub Releases.
* GitLab Releases.
* Direct download links.
* Discord attachments or download systems.
* Launchers that independently distribute the Software.
* Other mod-hosting websites.
* Third-party marketplaces.
* Torrents or other file-sharing systems.

This restriction applies regardless of whether the distribution is manual or automated — for example, a continuous integration pipeline configured to publish compiled builds to GitHub Releases or a similar service is a violation even if no person manually uploads the file.

A link to an authorized Permitted Platform page is permitted.

A source-code repository may contain the source code of a Fork for development and collaboration purposes, but this does not grant permission to provide unauthorized compiled downloads or other unauthorized distributions.

---

## 9. Derivative Works

Forks and derivative works are permitted, provided that they comply with this license.

A Fork may:

* Add features.
* Remove features.
* Change the user interface.
* Change the project's name.
* Change the project's branding.
* Change the project's implementation.
* Add additional code.
* Be substantially different from the original Software.

However, the Fork must still comply with the attribution, distribution, and monetization requirements of this license.

Additional code included in a Fork may be licensed separately where legally permitted, but such licensing may not be used to circumvent the restrictions applying to the original Software.

---

## 10. Dependencies and Third-Party Components

This license applies only to material owned by JustQuirk and distributed under the NPD License.

Third-party libraries, APIs, assets, dependencies, and other components remain subject to their respective licenses.

Nothing in this license grants permission to violate the license of a third-party component.

---

## 11. Trademarks and Branding

This license does not grant permission to use trademarks, logos, names, branding, or other distinctive marks belonging to JustQuirk or the original Software, except where such use is reasonably necessary to identify the Software or comply with the attribution requirements of this license.

Creating a Fork does not imply endorsement, sponsorship, partnership, or official status.

---

## 12. No Warranty

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

---

## 13. License Violations

Any distribution or use that violates this license is unauthorized.

Any violation of this license automatically terminates all rights and permissions granted under this license to the violating party, in addition to rendering the specific unauthorized act itself unlicensed. The copyright holder may, at their discretion, reinstate rights in writing.

The copyright holder reserves all rights not expressly granted by this license.

The copyright holder may, at their discretion, provide written permission for activities otherwise prohibited by this license.

Such permission must be explicit and may be limited to a particular person, project, version, platform, or use.

---

## 14. Changes to the License

The copyright holder may publish newer versions of the NPD License.

Unless explicitly stated otherwise, software already released under a particular version of the NPD License remains governed by that version.

The copyright holder may release future versions of the Software under a newer version of the license.

---

## 15. Acceptance

By distributing the Software or a Fork, the Distributor agrees to comply with the terms of this license.

Failure to comply with the terms of this license means that the permissions granted by this license do not apply to the unauthorized distribution.
