LunaCalc
Contact
LunaCalc is maintained as an independent calculator project. The site has no account or direct-message system, so email is the primary contact channel.
When reporting a calculation problem, include the tool URL, the values entered, the displayed result, the result you expected, and a screenshot if available. Please avoid including personal or sensitive information that is not needed to investigate the issue.
Use a clear subject line so we can identify the request quickly. Messages may be handled by the email providers involved in delivery.

We review messages as capacity allows and reply when possible. Complex calculation or display issues may take longer because they need to be reproduced and verified. Sending a message does not create a service contract or guarantee a response time.
