# Third-party licences

nexlore itself is licensed under the **GNU Affero General Public License v3.0** (see [LICENSE](LICENSE)). This file
lists what it ships or depends on.

## Bundled with the app

These files travel inside the container image, so their notices travel with them.

| What | Copyright | Licence | Notice in the app |
|---|---|---|---|
| Fonts Inter, Atkinson Hyperlegible Next, Literata, Source Serif 4, IBM Plex Sans, JetBrains Mono (via Fontsource) | their authors, see the notice | OFL-1.1 | `/licenses/fonts.txt` |
| Lucide icons (partly from Feather) | Lucide Icons and Contributors; Cole Bemis | ISC, MIT | `/licenses/lucide.txt` |

nexlore loads no font, icon or script from another host.

## Code taken over

`frontend/src/editor/listItemView.ts` is Milkdown's list item view (`@milkdown/components`, 7.22.2) with one change.
The notice ships with the app at `/licenses/milkdown.txt`.

## Backend

| Package | Licence |
|---|---|
| FastAPI, SQLAlchemy, pydantic, pydantic-settings, markdown-it-py, PyYAML, watchfiles, argon2-cffi, PyJWT | MIT |
| uvicorn, httpx, pypdf, segno, tinycss2 | BSD-3-Clause |
| numpy | BSD-3-Clause (with small parts under 0BSD, MIT, Zlib, CC0-1.0) |
| Pillow | MIT-CMU |
| python-multipart | Apache-2.0 |
| cryptography | Apache-2.0 **or** BSD-3-Clause |
| pillow-heif | BSD-3-Clause for its own code; the binary wheels are **GPLv2** as a whole, see below |

### HEIC photos: pillow-heif and the libraries it brings

To turn iPhone photos (HEIC) into WebP, nexlore uses pillow-heif. Its binary wheels, and so the container image,
contain:

| Library | Licence |
|---|---|
| libheif | LGPL-3.0 |
| libde265 | LGPL-3.0 |
| x265 | GPL-2.0-or-later |

The wheel ships these notices in `pillow_heif-*.dist-info/licenses/`. GPL-2.0-or-later and LGPL-3.0 may be combined
with an AGPL-3.0 work, and the source of every part is public.

## Frontend

| Package | Licence |
|---|---|
| React, React DOM, React Router, React Flow (`@xyflow/react`, the canvas; notice at `/licenses/xyflow.txt`), Milkdown (Crepe, Kit), Vue (used by Milkdown's components), CodeMirror language support, Lezer, marked, KaTeX, Mermaid, i18next, react-i18next, unist-util-visit, mdast-util-gfm-table | MIT |
| d3-force, yaml | ISC |
| Fontsource packages | MIT (the fonts themselves OFL-1.1, see above) |

Build and test tools (Vite, TypeScript, Tailwind CSS, Vitest, Playwright, ruff, pytest) are not part of the image.

## Compatibility

All of the above may be combined into an AGPL-3.0 work. The obligation runs one way: nexlore as a whole is
AGPL-3.0, and anyone who runs a modified version as a network service must offer its source.
