Additional Security

OK I am 61 years of age also a bloody minded Scotsman who likes to know where my pennies are at all times.
I run a top of the scale security on my tablet and on my mobile just for personal financial business also links to my banks but due to hacking etc I run a VPN 24/7 also an encrypted email address.

How would this crypto technology work alongside this VPN? Or am I assuming I would have to disable said VPN while using Crypto technology.
