Contact Tile calculators
A simple email route for corrections, source questions, privacy requests, and site feedback.
There is no contact form, ticket portal, phone line, or chat on this site. Email the administrator at admin@tilecalc.org.
For a calculator correction
Include the calculator URL, the values entered, the result shown, what you expected, and a source or reproducible calculation. Screenshots are useful when a label, unit, or formula is unclear.
For privacy or security
State whether you are asking about access, correction, deletion, or a security issue. Do not send passwords, payment details, identity documents, or unredacted client plans.
Response expectations
Messages are reviewed as time permits. This is an independent calculator site, not a staffed support desk, so there is no guaranteed response time and no promise that every suggestion will be implemented. Verified calculation errors are prioritized and checked against the relevant definition and tests.
