For example, you are using Signal on your smartphone and you link it to your computer using QR code feature (same as WhatsApp). By doing so, it would sync your account to your computer, but your chats will not be transferred. This happens because all the message history is stored locally on your smartphone. It means, if you lost your device you would not be able to restore any of your messages as you cannot back up on Google Drive or iCloud. 

Should I ditch WhatsApp and Switch to Signal?
