We read everything that comes in. The most useful message is a report that a number looks wrong.
Report a mistake in a result or a source
Email hello@projecttallykit.com and include:
- the calculator, or the page address
- the values you entered, including units
- the result you got and the result you expected, and why
- a link to the source, if you have one
Confirmed corrections are fixed and logged with their date on the methodology page.
Questions, suggestions and other messages
Use the same address for anything else: a calculator you would like to see, a problem using the site, or a privacy request. We reply in the order messages arrive, usually within a few working days. We are a small project and cannot give project advice, quotes or engineering opinions, and we will not be able to tell you how much material your specific job needs beyond what the calculators show.
Please do not send
Please do not send sensitive personal information. We only need the details of the calculation.
