I have never heard about that software.I don't advise using it either.No third party online/software tools should be trusted with your private keys unlike physical wallets.From what I understood,they offer saying of documents and stuff with a few encryption tools.In case you lose access to your saved passwords or specifically keys,they can recover accounts for you.This is bless and a curse.If they can recover such accounts,they can easily have access to your private keys.Its upto you to trust them or not.

You can use something GPG to encrypt text.

Alternatively, if you want some serious encryption software, I recommend that you checkout VeraCrypt(https://veracrypt.codeplex.com/). VeraCrypt is forked off of the now-defunct TrueCrypt which was one of the most popular encryption software.
