No. The Possibility Calculator does not connect to your bank and does not import transactions.
You choose what to enter. That means setup takes a little more thought, but it also means the calculator is not continuously reading your banking activity.
A simple way to begin
Use recent statements or your banking app to find the main recurring figures, then enter rounded amounts. You do not need to copy every transaction.
Worth knowing: If you see instructions elsewhere about connecting a bank feed, they do not describe the current product.
