The mautrix-signal developers grant the following special exceptions:
* to Beeper the right to embed the program in the Beeper clients and servers,
and use and distribute the collective work without applying the license to
the whole.
* to Element the right to distribute compiled binaries of the program as a part
of the Element Server Suite and other server bundles without applying the
license.
All exceptions are only valid under the condition that any modifications to
the source code of mautrix-signal (including signalmeow and libsignalgo) remain
publicly available under the terms of the GNU AGPL version 3 or later.
Note: mautrix-signal depends on libsignal, which is also licensed under the AGPL.
A license exception for libsignal must be acquired separately from Signal.
