# 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.
