- Not open source doesn't mean "non-safe"--that's a pretty dangerous and completely incorrect characterization
- The apps you list are literally the most non-safe services you could have possibly listed
- That's not what a wrapper is, I think you mean front-end
- Using the services at all means your data isn't protected, no matter which front-end you use the service collects your data, not the application you use
If you want to take your privacy seriously, then stop using these services. It's the service themselves that aren't privacy respecting, not the application in which you use to interface with them...
