Only two of the ones you recommended show up in the play store for me. Anysoft got really bad reviews. I tried Unexpected, but it lives up to its name. I didn't expect to need a read a manual to learn how it works. I've made sure futo doesn't have internet access and it hasn't sent any data according to android. I'm a Dvorak girl (even though it does make hilarious typos more likely on touchscreen) and its hard to find a good keyboard that works well with Dvorak.

Once fossify's one comes out of beta, I'll give it another go.
