GP here, with a late reply. Signal allows chats to be backed up and restored on Android. It does not support (and has said it won’t provide the feature) on iOS and related platforms that I mentioned. You can go through Signal’s help pages to confirm this yourself. If you use Signal on an Apple device and that device is either lost or broken, you’ll lose all your Signal messages when you setup a device again. That’s not necessarily the case with Android. Whatever you’ve written isn’t useful in this context.
