"the data is encrypted before it leaves your device, and is only decrypted after it's received by another of your devices"
How do I know this for sure? Is it possible to test? Sorry I just started using internet...
The issue isn't whether someone can intercept and decrypt, it's whether they can do that quickly enough for any information learned to still be useful. Taking any more than a few days to decrypt someone's SMS traffic usually isn't worth the effort - so as long as the encryption's that good it's usually good enough
Find it really hard to believe that someone can't just decrypt it in the middle and read my message. I don't care though, I am no spy.
