Signal doesn't store any of your chats at all. They're all on-device by design
Hm... If they're not being stored on the cloud, that means offline users would never receive messages, unless Signal is purely P2P. I haven't looked at the project, or the source, but I find it hard to believe -- you can't really do user lookups without some sort of middleware in the cloud.
All the data they have on any specific user is the account creation date, and the last online timestamp. They've already done loops around this topic in the DOJ.
And I thought it should be obvious that an online service doesn't work if you're offline
Yeah, but messengers, such as WhatsApp for instance, will send you missed messages once you're back online. That's what I was referring to.
