Contact

There is no contact form because a form would mean collecting and storing your details. You can email hello@squarefootcalcs.com for questions or requests. This address also handles questions about how a number was derived, accessibility problems, or anything about privacy and how this site handles data. Reports of a wrong figure are welcome if a bag yield, coverage rate or formula does not match what you found on the product, and requests for a calculator can be made by describing the job rather than the tool.
