# Licences

Everything this app is built from, and the terms it comes under. The app itself is MIT; see
[`../LICENSE`](../LICENSE).

The full text of each licence below also ships **inside the APK**, under
`assets/licenses/`, and is readable in the app at **Reading settings → About & licences**. The
SIL Open Font License requires the licence to travel with the software, so the font licences are
bundled rather than merely linked.

## Content

| What | Source | Terms |
|---|---|---|
| The poems | [ganjoor.net](https://ganjoor.net) | Classical Persian verse, long out of copyright |
| The data export | [ganjoor-data](https://github.com/anas-rashid/ganjoor-data) | **No licence file.** Worth asking upstream to add one |
| Poem search, first lines | `api.ganjoor.net` | A public web service. Its implementation, [GanjoorService](https://github.com/ganjoor/GanjoorService), is GPL-3.0 — this app uses none of that code, only data over HTTPS, so it is not a derivative work |
| AI summaries | Ganjoor's own feature, shown only when enabled | Labelled in the app as AI-generated |

Nothing in Ganjoor's repositories restricts AI-assisted use.

## Dictionary

Five sources, each row in the database tagged with the one it came from so the app can name it
and so any of them can be dropped without rebuilding the others.

| Source | Direction | Licence |
|---|---|---|
| [Wiktionary](https://en.wiktionary.org) | Persian → English | CC BY-SA 3.0 |
| [Wiktionary](https://en.wiktionary.org) | Urdu → English | CC BY-SA 3.0 |
| [Urdu Wiktionary](https://ur.wiktionary.org) | Urdu → Urdu | CC BY-SA 3.0 |
| [Wiktionary](https://en.wiktionary.org) | Arabic → English | CC BY-SA 3.0 |
| [Daneshjoo](https://github.com/0xdolan/Daneshjoo) | Persian → English | Repository states MIT |

Pronunciation — IPA with the variety it belongs to, and Urdu Wiktionary's vowelled spelling and
syllable split — comes from the same Wiktionary exports and carries the same licence.

Because four of the five are CC BY-SA 3.0, **the generated `dictionary.db` is CC BY-SA 3.0**.
Attribution is shown in the app beside every definition. See [`../tools/README.md`](../tools/README.md)
to rebuild it.

The Daneshjoo entry is worth a caveat: the repository states MIT, but the underlying lexicon is
a published Iranian dictionary, so that relicensing is worth verifying before relying on it.

## Artwork

The launcher icon — an eight-point *shamsa* — is original work for this project, MIT like the
rest of the code. Ganjoor's own app icons are unlicensed and are their mark; they are not used
here.

## Poet portraits

Fetched at runtime from `api.ganjoor.net`. They are Ganjoor's own illustrations of
long-dead poets, displayed as served and never redistributed in the APK.
