Trademark policy
"gunnar", the gunnar name, the gunnar logo, and the project's visual identity and official product designations are trademarks owned jointly by Vetra Automation AB and Ignalina ApS. All rights in them are reserved.
The software license is not a trademark license
gunnar's code is under AGPL-3.0-only and its original documentation under CC-BY-4.0. Neither license grants any right to use the gunnar trademarks. Trademark rights are separate from copyright, and are not licensed by this project.
You do not need permission to use the "gunnar" name for ordinary, truthful references — for example, to state that your project works with gunnar, is built on gunnar, or is a fork of gunnar. This is nominative, factual use and is fine.
Forks and derivatives
You are free to fork gunnar under the AGPL. When you do:
- You may truthfully state that your fork is "derived from gunnar", "based on gunnar", or "a fork of gunnar".
- You may not present your fork as an official gunnar release, as endorsed by or affiliated with Vetra Automation AB or Ignalina ApS, or in a way likely to confuse users about the source or official status of the software.
- Please rename a fork that you distribute or operate as a distinct product, so users are not misled into thinking it is the official gunnar. Do not use the gunnar logo or visual identity for your fork.
What requires permission
Using the gunnar name or logo in a way that suggests official status, endorsement, or affiliation — in product names, company names, domain names, logos, or marketing — requires prior written permission from Vetra Automation AB and Ignalina ApS.
