I would like to know how paired devices get synced together in Signal messaging app.
So this is what they say on their website
Signal messages, pictures, files, and other contents are stored locally on your device. These contents are readable by the open source Signal clients. Because everything in Signal is end-to-end encrypted, the Signal service does not have access to any of this data.
But let's say I have 2 devices synced together (phone + pc). The pc is off and I send multiple messages to multiple contacts on my phone. Then I turn off my phone and decide to use signal on pc. How is it possible that signal can sync all messages, pictures etc when my phone is turned off. They claim that everything is stored locally. So in theory, to be able to view my activity on the desktop signal app, the phone has to be connected to internet to sync with it.
Am I missing something ? I'm assuming signal desktop doesn't retrieve everything from all my contacts ..
