# Third-Party Notices

Portions of the English, French, and German profanity dictionaries in this
package are derived from the following upstream projects. Each project's
original license text is included in this directory.

| Source | Upstream | License | Used For |
|---|---|---|---|
| `obscenity` | [jo3-l/obscenity](https://github.com/jo3-l/obscenity) | MIT | English word list (originally sourced by obscenity from [cuss](https://github.com/words/cuss) © Titus Wormer) |
| `leo-profanity` | [jojoee/leo-profanity](https://github.com/jojoee/leo-profanity) | MIT | English word list (derivative of the Shutterstock LDNOOBW list) |
| `google-profanity-words` | [coffee-and-fun/google-profanity-words](https://github.com/coffee-and-fun/google-profanity-words) | MIT | English word list |
| `LDNOOBW` | [LDNOOBW/List-of-Dirty-Naughty-Obscene-and-Otherwise-Bad-Words](https://github.com/LDNOOBW/List-of-Dirty-Naughty-Obscene-and-Otherwise-Bad-Words) | CC-BY-4.0 | English, French, and German word lists (direct, attribution-required; see [`LDNOOBW.md`](./LDNOOBW.md)) |

## How this package uses the upstream data

- Only the raw word lists were consumed.
- Every imported term has been re-classified under this project's
  `severity` / `category` / `allowPartialMatch` schema.
- Many entries were dropped or tightened to preserve the project's
  zero-false-positive invariant.
- LDNOOBW terms that overlap with everyday vocabulary (e.g.
  `anal`, `butt`, `sex`, `intercourse`, `hardcore`) were deliberately
  excluded to preserve substring-collision safety.
- New LDNOOBW-sourced English entries live in the `LDNOOBW-SOURCED
  ADDITIONS` block in [`src/dictionaries/en.ts`](../src/dictionaries/en.ts);
  non-LDNOOBW extensions live in the `EXTENDED DICTIONARY (v1.1)` block
  in the same file. The French and German dictionaries
  ([`fr.ts`](../src/dictionaries/fr.ts),
  [`de.ts`](../src/dictionaries/de.ts)) are LDNOOBW-sourced in their
  entirety, curated to preserve collision safety and supplemented with
  a handful of common phrases not present in the upstream list.
