Hi, I'm sorry if my question is not in the right place. I would like to save notes (recipes, receipts, memories etc.) from my deceased father's Evernote to me. I have shared them and am able to use them from my account now but I'm wondering should I save them in some other form also. What happens if my father's account gets deleted at some point? (I don't have password for the account. I can use the account as long it doesn't log out in the mobile app.)
