I wasn't a telegram user for long so this may have changed but isn't the secret chat limited to device to device? So messages sent from my phone can't be decrypted by the same user account on my laptop? I just remember thinking, well this is dumb, and going back to Signal (Signal annoys me in other ways, requiring a single phone to be the "master" and other devices to be merely linked. I miss keybase, they had a great system including paper backups)
