Flectar Mail licensing
Flectar Mail is one open-source application. There is currently no separate “community edition”, “commercial edition”, or proprietary Flectar Mail client.
Open-source application
Unless a file or directory says otherwise, the Flectar-authored source code in
this repository is licensed under the GNU Affero General Public License,
version 3 only (AGPL-3.0-only). The complete terms are in LICENSE.
The AGPL permits use, study, modification, redistribution, and commercial use. When its conditions apply, distributors must provide corresponding source under the same license. Modified versions offered for remote interaction must also offer their corresponding source to those users.
Every client feature published in this repository, including integrations with optional hosted services, remains under its stated open-source license. Publishing a version under the AGPL is permanent: later business or licensing decisions cannot revoke the rights already granted for that version.
Optional paid services
Flectar may fund development by operating optional paid services that require ongoing infrastructure, such as hosted encrypted synchronization, relays, storage, managed processing, or support. A subscription purchases access to that service; it does not purchase a differently licensed Flectar Mail client.
The software and operational configuration used to run a Flectar-hosted service may be developed separately and may not be included in this repository. Merely communicating with an independent service over a network does not place that service in this repository or change the service's license. If a service does copy, modify, or derive from AGPL-covered code, the AGPL continues to apply according to its terms, including its network-source requirements.
No paid Flectar service or entitlement described here exists merely because it is mentioned as a possible business model. Any actual offering will have its own published scope, price, privacy terms, and service terms before launch.
Contributions
Outside contributions are accepted under the license that applies to the files
being changed, usually AGPL-3.0-only. Contributors retain copyright and must
have the right to submit their work under that license. See
CONTRIBUTING.md for the contribution process.
Trademarks
The software license does not grant rights to the Flectar name, the Flectar
Mail name, logos, application identifiers, or other brand assets. Forks remain
welcome under the AGPL, but distributed modified versions must follow
TRADEMARKS.md, including the renaming requirements.
Third-party material
Dependencies, vendored components, fonts, and example brand marks retain their
own licenses and notices. They are documented in
THIRD_PARTY_NOTICES.md and the LICENSES/
directory. Flectar cannot offer commercial rights to material it does not own.
