You and me have different views about privacy. I think you should have control over your data. Google indirectly provides your email information to advertisers. Example: You receive a flight notification. Google reads your email and targets you with ads related to your trip(i.e. hotels, things to do etc based on your age, gender etc) though various channels(i.e. gmail UI, google search, Google Now/AI etc). It wants to do the same with this Allo application. The encryption they claim it's in place it's worthless because it doesn't protect you from this. They try to claim your data is `private` because it's encrypted. The other case which is uglier is that Google gives your data to foreign governments or other agencies. This may have great consequences. Cloud computing is based on trust and it's possible because the main players(i.e. US government, cloud providers such Amazon) are trusted not to spy their clients but I don't see many rushing to a chinese cloud vendor to host critical data(i.e. email) on their servers. The security and privacy features we have are currently based on the good will of the provider (i.e. Google). If we talk about encryption of personal data I think it's worth to ask a bit more than a buzzword. One such thing is to do not share the encryption keys.
