Tax is private. Asking you to sign in to do the maths is a small betrayal of that.
Most fintech products treat signup as the front door. Type your email, accept the terms, and only then are you allowed to see anything. That model works for the company collecting the emails. It does not work for the person who just wants to know how much they keep.
We picked the opposite. Show up, type a number, get a real answer. You do not have to introduce yourself to us first.
Anonymous is not a degraded experience here.
The full calculator, the band-by-band breakdown, the currency-switching, the comparison with the old law, and every guide on the site are available to anonymous visitors. We do not lock features behind a signup wall. We do not nag mid-flow. We do not interrupt your result with a modal.
When accounts arrive, they will be optional.
Any future account feature — for saving scenarios across devices or opting into reform alerts — will use magic-link sign-in only. No passwords, no social login. Even then, the anonymous calculator stays anonymous. You will not be asked to sign up to use it. You will not be prompted to sign up after a result.
