Are the tools really free?
Yes. They are free to use, with no sign-up. The two checklist tools let you optionally send us your result if you want help.
Is my data stored?
The calculators, generators and previews run in your browser. Checklist ticks are saved only in your browser. Nothing reaches us unless you choose to submit a form.
Can I rely on the results?
They are practical guides, not guarantees. Tax rules, search results and AI answers change, so confirm important decisions with a professional.
