Damn, Dabek is great speaker!
Congrats dude for getting into safex, it's good choice!
If I understand: there is no wallet for phone yet, just desktop for now. I suggest to keep your coins in safex wallet. Yeah, you should have your private address extracted (printed/copied on piece of paper-that's how most of people is doing it, it's the simplest option) and it's gonna be yours forever! If you are having copies of keys on your laptop/pc, be careful who has access to it...
