Open source
Free software, in the open
Helia, Annora and Valerian are free software. You can use them, read how they work, change them and share them.
The licence
GPL, with a few additional terms
The apps are released under the GNU General Public Licence, version 3 or any later version. On top of that, two additional terms apply under section 7 of the licence:
- The author’s name and the dedication must be kept, in the source and in the About page of the app.
- A changed version must say it is changed, and must not be presented as the original or as made or endorsed by me.
The full text is in the source of each app. If you would rather have it in plain words, read why the apps are free.
Where the source comes from
With every build, and on GitHub
Each build on 12hobbies.studio has its source code beside it, as a download you can check against its SHA-256 checksum. The previous version is on GitHub, under qisback: Helia, Annora and Valerian.
I build and test the apps on my own system first, and GitHub is a published copy of the source. For that reason I am not taking code contributions at the moment. Bug reports and ideas are welcome as GitHub issues.
Paid add-ons
The add-ons are closed
A few optional extras, such as AI denoise and sharpen and remote processing, are closed source and need a key. They are separate from the apps, which stay free software, and the GPL code is not changed by them.
There are three ways to get the apps: Free, Supporter and Pro. What each one includes and what it costs is on the 12hobbies.studio download page.
Logos and data
Not everything is GPL
The Mundil, Helia, Annora and Valerian logos are not covered by the GPL. They are copyright Laurence Horrocks-Barlow, all rights reserved. You may use them unmodified in unmodified builds and to refer to the projects. Forks and changed versions need their own branding.
Some data has its own licence. For example, Valerian’s star colours use the Gaia catalogue, which is a separate free download with its own terms.
