Save the site and create paperwallet offline, that way there should be zero chance of it being intercepted/recorded by anyone really.
I myself too have bitcoins in savings, but i stored them using a different method;
- i download core to fresh install OS, create wallet, send funds to that wallet address
- copy wallet.dat to fresh formatted thumbdrive (x3 backups), and formatted that system afterwards
- move the funds from online comp always to that savings one til the day i want to use them
Might be tricky if ure planing to use the funds, but if u're having separate longterm holdings like me, the process is to be done only once and it's not much of a hassle.
cheers
