How quickly do you reply?

Can I book a walkthrough?
Yes, choose "A 20-minute walkthrough" in the form and suggest times; we reply with a confirmed slot.
Is there a phone number?
Not at the moment. Email and the form reach the same team and leave a written record.
Where do I report a wrong figure?

I'm a client of a firm using your calculators. Who do I contact?
The firm whose website you used; they own the information you sent. For privacy requests about our handling, see your privacy choices.
Can you help with my taxes?
No. We build calculators for firms and don't give tax, legal or investment advice.
What happens to what I send?
It's used only to reply to you. See the privacy policy.
