Huh? After visiting the BudgetDuo site, I’d definitely say that a traditional spreadsheet is easier and more organized.

Even more important is that I know my data would remain private and I would not have to trust a third party like BudgetDuo to be a safe steward of any of the data about shared expenses.

Huh? You're in the minority here if you're saying that people would rather use a spreadsheet than web/mobile app. How can more than one person see or update their shared expenses if the Excel spreadsheet resides on your partner's computer? That doesn't sound easy to me.
