Do you believe that whatsapp is not storing your messages now ? They said they are not doing it to begin with but there are good reasons that they might be doing this. Fb and whatsapp have shared enough information to be fined by an EU court this week for 100 million euros. Although 've to agree that data with US is better than Russia.
Regarding "fined by the EU". They obviously transferred WhatsApp data to Facebook and vice versa.
But I don't think that they necessarily store all of your WhatsApp messages somewhere in the cloud. Otherwise they could provide a similar easy, device independent solution like Telegram - instead of using the smartphone as a general pipe for all of the messages. So yeah...maybe they do and maybe they just don't want to tell us - but for now I am pretty confident that they would provide their user base with some kind of storing back end advantages.
