# Third party notices

Blockslot uses the following third party work. Their licenses are reproduced in
full below, as those licenses require.

## ludusavi and ludusavi-manifest

Blockslot invokes `ludusavi` to perform backups and restores, and derives its
game index from `ludusavi-manifest`.

- https://github.com/mtkennerly/ludusavi
- https://github.com/mtkennerly/ludusavi-manifest

Blockslot does not contain or redistribute the ludusavi program. The Decky
plugin names the official v0.31.0 release as a download, and each device
fetches it from ludusavi's own release page. The licenses of everything
compiled into that program are published beside it, as
`ludusavi-v0.31.0-legal.zip`:

- https://github.com/mtkennerly/ludusavi/releases/tag/v0.31.0

Both are licensed as follows.

```

Blockslot's game index is derived from `data/manifest.yaml` in
`ludusavi-manifest`. It is a subset, reshaped for size and load speed. The
original data is unmodified in substance.

## PCGamingWiki

`ludusavi-manifest` is compiled from data on
[PCGamingWiki](https://www.pcgamingwiki.com), whose content is licensed
[CC BY-NC-SA 3.0](https://creativecommons.org/licenses/by-nc-sa/3.0).

Blockslot takes that data through `ludusavi-manifest` under its MIT license and
does not claim rights over the underlying facts. This credit is not required by
MIT. It is here because the save file locations in that wiki were found and
recorded by people, one game at a time, and that work deserves naming.

## Garage

The BlockSlot server image (`blockslot-server`) includes
[Garage](https://garagehq.deuxfleurs.fr), the S3 store the saves live in,
copied unmodified from the official `dxflrs/garage` image. Garage is
Copyright Deuxfleurs and its contributors, licensed under the
[GNU Affero General Public License v3.0](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/main/LICENSE).
Its source code, for the exact version in the image (named by
`GARAGE_VERSION` in `server/Dockerfile`), is at
<https://git.deuxfleurs.fr/Deuxfleurs/garage>. BlockSlot runs Garage as a
separate program and talks to it only over its S3 and admin HTTP APIs;
BlockSlot's own code stays under the MIT license.

## Syncthing

Older BlockSlot setups moved files with [Syncthing](https://syncthing.net/),
and the Syncthing screens remain for them. BlockSlot does not bundle or modify
it. Syncthing is licensed
[MPL-2.0](https://github.com/syncthing/syncthing/blob/main/LICENSE).
