Interesting idea!

So basically we'd hold the data hostage ;) I'm curious - why is that's a better model, in your mind?

We support users if they get audited in the sense that we'd give them all of their data recorded with Keeper and help answer any questions. Ultimately, we base all of our suggestions on information the user has told us, but we can't guarantee that the answers were truthful.

I'm curious - what tax software do you use, and what's their audit claim?
