As far as I know there is not any. I have asked people also. (I read tech blogs from Turkey and they never mentioned one). Maybe that people are Turkish people who live in US already? (I consider you didn't want to mention their name.
First Encryption. Encryption is so important since I wouldnt want to save my financial informations into a cloud service. I know that evernote doesn't use an integrated solution for this. (You just need to encrypt your notes one by one)
Second: Encryption (again)
Third: Third way to access my files if one forgets email/password. Sometimes people might lose access to their emails. This way, If I forgot the evernote's password, then I cant get access back to evernote.
4th: Might be ligher than evernote. The software should be as light as "notepad". I can open 100 notepad windows and doesnt consume much memory. And most important notepad never crushes..
