public/ is copied verbatim into the build, src/assets/ is not - so the fonts were deployed without the license texts that OFL-1.1 and Bitstream Vera require to travel with them. Moving the texts to public/font-licenses/ fixes that with no build step. The notices covered only Liberation and missed five bundled dependencies; the commercial license now states what it cannot relicense, the copyleft German dictionary and thesaurus above all.

# Commercial License
|
|
|
|
EdenText is **dual-licensed**.
|
|
|
|
## 1. Open-source license (default)
|
|
|
|
By default, this software is licensed under the **GNU Affero General Public License
|
|
v3.0 (AGPL-3.0-only)** — see [`LICENSE`](./LICENSE). You may use, modify, and
|
|
distribute it for free under those terms.
|
|
|
|
The AGPL is a strong copyleft license. Among other things, it requires that **if
|
|
you run a modified version and make it available to users over a network, you must
|
|
make the complete corresponding source code of your version available to those
|
|
users.** It also requires that derivative works you distribute be licensed under
|
|
the AGPL as well.
|
|
|
|
## 2. When you may want a commercial license
|
|
|
|
The AGPL may be incompatible with your needs if you want to:
|
|
|
|
- embed this editor in a **proprietary / closed-source** product or service,
|
|
- distribute a modified version **without** releasing your source code,
|
|
- offer it as part of a **hosted/SaaS** product without the AGPL's network-source
|
|
obligations, or
|
|
- obtain a warranty, indemnification, or commercial support.
|
|
|
|
For these cases, a **separate commercial license** is available that removes the
|
|
copyleft obligations of the AGPL, under negotiated terms.
|
|
|
|
## 3. What a commercial license does not cover
|
|
|
|
A commercial license covers the copyright holder's own work. It cannot change the
|
|
terms of third-party components, which keep their own licenses either way —
|
|
[`THIRD-PARTY-NOTICES.md`](./THIRD-PARTY-NOTICES.md) lists them all. Two points
|
|
matter for a proprietary distribution:
|
|
|
|
- The **fonts** (SIL Open Font License 1.1, and a Bitstream Vera-licensed subset)
|
|
may be bundled in proprietary software, provided their license files travel
|
|
with them.
|
|
- The bundled **German dictionary** (igerman98) is **GPL-2.0-or-3.0** and the
|
|
**German thesaurus** (OpenThesaurus) is **LGPL-2.1-or-later**. These are not the
|
|
copyright holder's to relicense. They are separate data files that the app loads
|
|
at runtime, not part of its code, so a proprietary distribution may either keep
|
|
them under their own copyleft terms or omit `public/dictionaries/de` and
|
|
`public/thesaurus/de` — the app then offers no German spell check or synonyms.
|
|
The English data is permissively licensed and unaffected.
|
|
|
|
## 4. How to obtain a commercial license
|
|
|
|
Commercial licenses (including subscription terms for organisations) are granted
|
|
by the copyright holder on request.
