# Licensing

Copyright (c) 2026 42labs.

Entropy for Firefly III is dual-licensed.

1. **Open source** — [GNU Affero General Public License v3.0](LICENSE) (AGPL-3.0).
   Use it, run it, modify it, self-host it. If you run a modified version as a
   network service, the AGPL requires you to offer your users its source.

2. **Commercial** — to use Entropy for Firefly III without the obligations of the AGPL-3.0
   (for example, in a closed-source or SaaS context), a commercial license is
   available. Contact <ahoy@42labs.io>.

`LICENSE` holds the verbatim AGPL-3.0 text and nothing else, so that GitHub — and
every tool that reads a licence by matching it — identifies the project correctly.
The dual-licensing terms live here.
