Question: How long is it OK to leave the primary offline? #1553

First thanks for signal-cli!

Holidays are near, and my primary device is a laptop that I won't bring with me.

Reading the README:

The Signal protocol expects that incoming messages are regularly received (using daemon or receive command). This is required for the encryption to work efficiently and for getting updates to groups, expiration timer and other features. I understand that some signal feature needs for the primary to connect from time to time.

Reading the signal website:

Your phone does not have to be online for the linked device to work, but it will unlink after 30 days of inactivity.

Which I translate to "Your primary device does not have to be online for your secondary device to work".

So it feels like it's OKish to have it's primary offline for a week or two as long as one does not use features like group chats. Has anyone tried this so we could enhance the README about that point?

I've had no issues when not touching my "primary" device for months at a time, only using the linked signal-cli and signal-desktop.

Yeah, the primary can be offline for longer. At some point the Signal-Server will mark it as unregistered. I think it's a year, but I'm not sure.
