Best app I have tried – Accounts 2 Checkbook Review

Exceedingly happy with the checkbook app. I have a question I’m hoping the developer can answer because I can’t find the answer anywhere. I had a checking account that I closed in December 2016. If I delete that account from my app, what happens with the transactions and income/expense history in the app? Please advise.
