[Replicant] signal app

[dllud]

Hi Fil,

If I remember correctly Signal uses Google Cloud Messaging or other similar Google service for push messages. Thus it depends on the non-free Google Play services. That's the reason why it isn't available on F-Droid.

Furthermore Signal is a centralized service, with all clients connecting to the same server, operated by the Signal developers. The server software, although free software, does not allow for federation.

I strongly advise you to use Conversations ( https://f-droid.org/app/eu.siacs.conversations  https://conversations.im/ ) instead. It is a XMPP client with support for encryption (OMEMO) and push messages.
XMPP is a federated messaging protocol that allows anyone to run it's own server, much like email. XMPP now has an extension for push messaging, directly from the server to the client, with no need to rely on proprietary Google services. Many community-run servers support that already: https://compliance.conversations.im

For the PC you can use Gajim: https://gajim.org/

Regards,
David
