Why "private by design" matters
Many financial websites ask for your income, debts and email before showing a result — and that data can end up with lenders and marketers. Our calculators are plain JavaScript that run on your device, so there's nothing to collect. If you want a human to look at your numbers, you choose to share them through our advisor matching form.
